As the solemn procession of Leng Feng and his elite special operations team returns home with the remains of a fallen comrade, an unsettling atmosphere envelops the community. The family's efforts to prepare for a funeral clash dramatically with the cold, calculated ambitions of a real estate company determined to raze the very home where cherished memories will soon be laid to rest. The arrogant boss of this heartless corporation belittles Feng and his team, demonstrating disdain for their patriotism. However, his contempt swiftly turns to fear, as Feng's furious retaliation leaves him sprawled on the ground, his goons dispatched in a heartbeat by the skilled special operatives. Shortly after, authorities intervene, commanding Feng to cease his actions, though not before he delivers a blow of justice to those who provoked him.
Following his release from military prison, Feng embarks on a new and aimless journey to Africa, where his mercenary skills come into play when he thwarts a hijacking attempt by Somali pirates. Utilizing his hand-to-hand combat expertise, he successfully subdues the attackers. Over the course of three years, Feng has carried a bullet—an ever-present reminder of the mysterious fate of Lieutenant Colonel Long Xiaoyun, who was kidnapped.
A fateful encounter at a beach party sets off a chain of events that plunges Feng into chaos. An unprovoked assault by rebel factions intent on destabilizing the African nation casts him into a whirlwind of destruction. As rebel forces overpower government troops, a Chinese fleet arrives to rescue its citizens. In the midst of this turmoil, a shopkeeper, whose life Feng saved, reveals that the bullet he carries is linked to European mercenaries backing the rebels. This revelation spurs Feng on a mission to rescue factory workers and Dr. Chen, a key hostage at a nearby hospital, who is tirelessly striving to create a vaccine for Lamanla, a deadly disease decimating the region. Feng faces this perilous endeavor solo, as his comrades are hindered by strict military protocols preventing their presence on foreign soil.
Upon reaching the hospital, a frantic hostage rescue mission unfolds amidst pandemonium. Tragedy strikes when Dr. Chen becomes a victim of a brutal rebel assault, imploring Feng to look after a young African girl named Pasha, one of his patients with rare immunity to Lamanla. Amidst the horror, Feng, along with a surviving medic Rachel Smith, manages to escape with Pasha, though Feng sustains a grievous wound traversing a gruesome landscape littered with infected bodies.
With his godson’s mother among those endangered at the Hanbound factory, Feng undertakes a desperate mission to rescue both her and the other workers from the brink of disaster. Upon arrival, he encounters hostility from Zhuo Yifan, the factory owner’s son, a fervent admirer of Chinese military might. Feng informs the workers that a helicopter rescue team is en route to evacuate women and children while the men are to travel by road to safety.
However, Big Daddy’s mercenary unit, hired by Dyon Corps, has other sinister plans. On the hunt for Pasha, whom they believe holds the secret to a cure for Lamanla, Feng rallies the workers to defend their families against this new threat. Just as despair looms large, Big Daddy’s men receive orders to retreat—revealing that the rebel leader abstains from harming the Chinese, recognizing the necessity of their support for future power.
Big Daddy, however, has taken matters into his own hands. He assassinates his leader and assumes authority, demanding that the factory workers be captured and Pasha eliminated. Meanwhile, as the truth about Feng's condition circulates among the workers, it shocks them to discover he is infected with Lamanla. Rachel intervenes, administering a vital serum, disclosing that Dr. Chen discovered a cure using patients who gained immunity through exposure to the virus—Pasha being one of them and not his biological daughter, as initially presumed.
As the dust settles over the brutal battleground of Hanbound, Big Daddy and his cohorts regroup, managing to capture some surviving workers. Yet, empowered by determination and flanked by Rachel and Pasha, Feng embarks on a daring mission to rescue the captives. Their efforts prove fruitful, as they succeed in extracting workers from looming peril. However, their moment of respite is cut short when a rescue helicopter, carrying women and children to safety, is shot down by enemy fire.
In the ensuing chaos, Feng and his allies face a relentless onslaught from Dyon Corps' mercenaries and rebels, bolstered by the arrival of armored tanks. The gravity of the situation does not go unnoticed; the Chinese fleet responds with pinpoint missile strikes, systematically decimating the tanks and altering the course of the battle. Amidst the turmoil, Feng confronts Big Daddy, only to learn a harrowing truth: the bullet responsible for Xiaoyun's death was fired from Big Daddy's weapon. Enraged by grief, Feng unleashes a savage beating on his adversary before ultimately defeating him in a brutal showdown.
As the immediate threats dissipate, Feng rises to lead the surviving group, guiding them through treacherous rebel territories toward the safety of a UN camp. The film concludes with a poignant visual of a Chinese passport and an inspiring message: “Don't give up if you run into danger abroad. Please remember, a strong motherland will always have your back!”
As the credits roll, a mid-credits scene introduces a shocking twist—Feng’s commander permits him to rejoin his military squadron, only to present a disturbing video, unveiling that Xiaoyun is, in fact, still alive, leaving Feng grappling with newfound questions and uncertainties.
