As the Second World War intensifies, President Roosevelt receives a pressing request from Colonel Steve Trevor (Chris Diamantopoulos), urging him to mobilize the United States by forming a remarkable assembly of extraordinary heroes known as the Justice Society of America. This exceptional group includes Trevor, Black Canary, Hawkman (Omid Abtahi), Hourman (Matthew Mercer), and Jay Garrick, all led by the unstoppable Wonder Woman (Stana Katic). Their imperative mission is to confront the looming Nazi threat, utilizing their distinctive abilities to secure peace around the globe.
In a contrasting present-day scenario, Barry Allen (Matt Bomer) and Iris West (Ashleigh LaThrop) are enjoying a peaceful picnic in Metropolis, attempting to escape the pressures of their everyday lives. Their serene outing is abruptly interrupted when Superman (Darren Criss) arrives, engaged in a fierce conflict with Brainiac. Instinctively, Allen transforms into his swift alter ego, The Flash, and rushes to support the Man of Steel by harnessing his remarkable speed. Just when Brainiac fires a Kryptonite-laced bullet, Allen dives into the Speed Force for the very first time, successfully grasping the projectile and feeling the guidance of a mysterious voice during this life-altering moment.
As the energies of the Speed Force fade, Allen is catapulted to what he perceives to be the past, amid chaos as the Justice Society of America battles the Nazi forces. Initial confusion soon dissipates as the JSA identifies him as an ally, determining that Barry originates from a different timeline.
The JSA’s next undertaking involves infiltrating a heavily fortified Nazi stronghold to rescue a codebreaker whose deciphering expertise could reveal secrets stolen by Trevor. Aware of the potential risks of triggering a temporal paradox, the heroes cautiously welcome Allen’s assistance.
As they breach the fortress, led by “Shakespeare” (Darren Criss), they combat numerous challenges and uncover prisoners in distress within the dungeons. One battered captive, who recognizes Shakespeare as Clark Kent, passes along a parcel containing a costume and conveys a critical message: he must prevent an impending catastrophe. When a guard launches an attack on Shakespeare, the bullets harmlessly ricochet off him, unveiling his true identity to Allen. Barry then realizes that this isn’t the familiar Clark Kent he knows; instead, it is an alternate reality version.
Upon finding the codebreaker, Hawkman recognizes him as Kent Nelson, also known as Doctor Fate (Keith Ferguson). Allen soon learns that Fate has been a mysterious guide throughout his journey, hinting that Barry must undergo a significant lesson and complete a vital mission before he can return home.
Following Fate’s obscure advice, the team sets its focus on the Bermuda Triangle, where the codebreaker’s expertise will help decode a crucial message. As they navigate this perilous region, Doctor Fate inexplicably vanishes, leaving Allen with an unsettling mix of hope and trepidation.
As the Justice Society of America’s submersible craft, the Triangle, nears its target, a swarm of Nazi warships detects them. A flurry of depth charges severely damages their engines, obliging The Flashes and Wonder Woman to act decisively. With enemy vessels closing in, they execute a bold counterattack, with Wonder Woman leading the charge against the Nazi fleet. Just when all seems lost, Atlantean soldiers appear, guiding the heroes to a nearby outpost where they encounter Aquaman. However, they soon discover that their supposed rescue is part of a sinister trap set by Aquaman himself. In the shadows, the Advisor (Geoffrey Arend), a cunning telepathic mercenary, pulls the strings, aligning the Atlantean forces with the Nazis to eradicate the JSA and seize dominion over the Earth.
As the stakes reach critical heights, the Flashes unite to break free from their dire situation, dispersing to confront the challenges on separate fronts. One team ventures to New York City to thwart the Nazi-Atlantean alliance while Barry and Wonder Woman aim to stop Aquaman from unleashing a horde of monstrous creatures lurking in the depths.
The confrontation over Manhattan spirals into an explosive battle, with the JSA bravely holding their ground amid unrelenting odds. Initially, they suffer setbacks against the Atlantean forces; however, the arrival of the sea monsters shifts the dynamics dramatically. With Hawkman incapacitated and Hourman wounded, it falls to Garrick and Canary to vanquish these titanic beasts and change the course of the fight.
Simultaneously, Wonder Woman and Allen engage Aquaman in a fierce confrontation. Utilizing her Lasso of Truth, Wonder Woman severs the Atlantean king’s connection to the Advisor, allowing him to regain control. Ashamed, Aquaman retreats and signals his troops to withdraw. However, the Advisor ominously reveals that an aerial strike by Nazi bombers is imminent before meeting a brutal end at Barry’s hands.
As the aftermath unfolds, Kent returns donning the costume gifted by Trevor, embarking on a mission to dismantle the incoming bombers. In a heartfelt moment, Trevor proposes to Wonder Woman, who gracefully accepts. Although the Advisor’s body is later found, he ultimately eludes capture, raising the specter of further vengeance against the JSA.
As Barry prepares to make his way back to his own Earth, he bids farewell to the Justice Society, receiving a ring from Trevor as a treasured reminder of their bond. With this memento, Wonder Woman cautions him to seize the moment without delay. Back in his familiar realm, Barry channels his speed alongside Garrick’s, propelling himself back in time just moments before he originally intervened to save Iris. After triumphing over Brainiac yet again, Barry proposes to his beloved, who joyously accepts.
In the wake of these monumental events, the JSA pledges to pursue justice for Trevor’s heart-wrenching loss, while Barry gazes into a promising future, advocating the creation of a superhero coalition dedicated to tackling threats across multiple dimensions. With Iris at his side, he embarks on a quest to transform this ambitious vision into a compelling reality.

Barry Allen travels to 1940 while experiencing the Speed Force for the first time. When Brainiac fires a Kryptonite-laced bullet at Superman, Barry dives into the Speed Force to intercept the projectile. The mysterious voice guiding him throughout his journey belongs to Kent Nelson (Doctor Fate), who draws Barry to this specific time period to assist the Justice Society with their critical mission.
The voice guiding Barry in the Speed Force is first heard when he catches the Kryptonite bullet, hinting at Doctor Fate's involvement before Barry even realizes it.
The Advisor is a cunning telepathic mercenary who manipulates Aquaman into aligning the Atlantean forces with the Nazis. His goal is to help the Nazis eradicate the Justice Society of America and seize dominion over Earth. He controls Aquaman through mental manipulation, forcing him to set a trap for the heroes. The Advisor ominously reveals an imminent Nazi bomber strike before being killed by Barry.
The Advisor's presence is hinted at when the Atlantean rescue turns out to be a trap, showing his manipulation began earlier than the heroes realized.
Wonder Woman uses her Lasso of Truth to sever the Advisor's telepathic connection to Aquaman. This act frees the Atlantean king from the mercenary's mental control, allowing Aquaman to regain his senses. Ashamed of his actions under manipulation, Aquaman signals his troops to withdraw and retreats, ending the Nazi-Atlantean alliance.
The Lasso of Truth's power over mind control is established earlier when Wonder Woman uses it to compel honesty.
Doctor Fate (Kent Nelson) serves as Barry's mysterious guide because Barry needs to learn a vital lesson before returning home: to seize the moment. Fate cryptically directs the Justice Society toward the Bermuda Triangle to decode a critical message and helps orchestrate the events that will teach Barry about courage and taking action. This guidance prepares Barry for his ultimate decision to propose to Iris.
Doctor Fate vanishes at the Bermuda Triangle after delivering his cryptic instructions, his purpose fulfilled in Barry's journey.
After experiencing the events of 1940 and learning from Doctor Fate that he must seize the moment, Barry returns to his timeline moments before Brainiac attacks again. He defeats Brainiac once more, then proposes to Iris, who accepts. This represents Barry's growth from someone who hesitates to act to someone who takes decisive action in both heroics and love.
Wonder Woman's warning to Barry as he leaves, 'Seize the moment', directly foreshadows his proposal decision.

Their relationship has developed throughout the mission, and Trevor seizes the moment to ask her to marry him. Wonder Woman gracefully accepts, marking a romantic conclusion amid the wartime heroism.
The growing bond between Trevor and Wonder Woman is evident throughout the mission as they fight together.
The sea monsters that arrive during the battle over Manhattan are controlled by the Advisor as part of his larger plan. Though the Advisor is killed before fully executing his scheme, the sea monsters were programmed to attack anyone, including the Atlanteans themselves. This turn of events helps the JSA gain the upper hand, with Jay Garrick and Black Canary defeating the creatures and shifting the battle's outcome.
The Advisor's ominous reveal about the imminent bombing suggests he had multiple contingency plans that went awry.
The Justice Society travels to the Bermuda Triangle to decode a critical message using the codebreaker they rescued, Kent Nelson. This message contains vital intelligence that helps the heroes understand the full scope of the Nazi-Atlantean plot. The mission is crucial because it provides the information needed to counteract the enemy's plans, though Doctor Fate vanishes during this journey after delivering his final instructions.
Doctor Fate's cryptic guidance toward the Bermuda Triangle establishes its importance before the team even arrives.
When bullets harmlessly ricochet off Clark Kent during the fortress infiltration, Barry realizes this is an alternate reality version of Superman, not the one he knows from his timeline. This revelation confirms that Barry has traveled to a different timeline entirely, where an alternate Justice Society operates during World War II.
The prisoner recognizes Clark Kent as 'Shakespeare' and calls him by a different name, hinting at the reality shift before the bullet proof reveals Clark's identity.
Steve Trevor gives Barry a ring as a memento of their bond and shared mission. This ring serves as a physical reminder of Barry's journey through time and his alliance with the Justice Society. Wonder Woman uses this moment to deliver her final advice: to seize the moment without delay, which directly influences Barry's decision to propose to Iris upon returning home.
The ring symbolizes the connection between different eras of heroes and foreshadows Barry's commitment to building a new coalition.
After working with the Justice Society and witnessing threats that span multiple dimensions, including the Nazi-Atlantean alliance and the Advisor's schemes, Barry recognizes that Earth needs a unified team of heroes to tackle threats across different dimensions. With Iris supporting him, Barry envisions creating a superhero coalition that can respond to multiversal dangers, setting up the foundation for future heroic teams.
Barry's experience with the JSA demonstrates the effectiveness of teamwork against large-scale threats.
Before Barry kills the Advisor, the mercenary ominously reveals that an aerial strike by Nazi bombers is imminent, posing a final threat to the heroes and civilians. This revelation raises the stakes even in the Advisor's dying moments. Meanwhile, Kent Nelson dons his Doctor Fate costume gifted by Trevor and embarks on a mission to intercept and dismantle the incoming bombers, addressing this final danger.
The Advisor's final threat underscores the ongoing nature of the Nazi menace even after the main battle concludes.
Still wondering what the ending of Justice Society: World War II (2021) really means? Here’s a spoiler-heavy breakdown of the final scene, major twists, and the deeper themes that shape the film’s conclusion.
The ending of “Justice Society: World War II” reveals that the Flash, after traveling through the multiverse, manages to return to his original universe just in time to prevent Superman from being fatally hit by a Kryptonite bullet. His journey highlights the complex nature of the multiverse, where different Earths exist with their own versions of familiar heroes. During the adventure, Flash learns that he’s not just in a different period of history but in an entirely different universe, which deepens his understanding of how interconnected and layered the multiverse truly is.
Throughout his journey, Flash exposes the crucial role of the Speed Force—an energy source that grants speedsters their powers—which becomes divided when two speedsters exist in the same universe, causing a decrease in their abilities. This concept underpins much of the action, emphasizing how the multiverse influences even the fundamental forces of superpowers.
As the Justice Society fights to stop the Nazi plans for ancient mystical artifacts that could turn the tide of WWII, they encounter major threats like a mind-controlling advisor who manipulates Atlantean forces and unleashes chaos. Despite losing some heroes like Hawkman and Steve Trevor in the process, the team ultimately succeeds in preventing these catastrophic plans, thanks to the timely arrival and intervention of Superman, who is brought into the fray by Doctor Fate’s prediction.
Using his incredible speed, Flash creates a portal that allows him to return to his own universe. Back home, he manages to save Superman from the deadly Kryptonite bullet and suggests forming a new league of heroes to safeguard the world, symbolizing hope for future teamwork. The story closes with Flash proposing to his girlfriend, signaling a new chapter in his personal life and hinting at the birth of a broader, multiverse-spanning Justice League.
The film subtly introduces viewers to the concept of the multiverse and the Speed Force, setting the stage for even greater cosmic adventures within the DC Universe. It combines action, humor, and heroism to leave fans excited for what lies ahead, affirming the potential for more interconnected stories across different worlds. Overall, it’s a compelling blend of history, heroism, and the endless possibilities of the multiverse, culminating in a hopeful outlook for DC’s future of storytelling.
