Max, a curious and adventurous young boy played by [Jacob Tremblay](../actor/jacob-tremblay), starts his day immersed in a fantasy online game, where he amusingly modifies the appearance of an orc before preparing for a private moment. His father, lovingly portrayed by [Will Forte](../actor/will-forte), enters to inform him about a weekend trip and warns him to be cautious with a new drone he has gifted him. As Max is about to engage in a private act, his father unexpectedly walks in and gently interrupts, giving him "the talk" about privacy and boundaries. This moment leaves Max feeling embarrassed but also provides a humorous reminder about growing up.
Later, Max spends time with his best friends, [Brady Noon](../actor/brady-noon) as Thor and [Keith L. Williams](../actor/keith-l-williams) as Lucas, collectively known as “The Bean Bag Boys.” They gather at Thor’s house, where typical childhood annoyances occur, especially from his younger sister Annabelle. During their hangout, the boys stumble upon a valuable baseball card—worth up to $600—that sparks their excitement over possible quick riches.
The next day, the friends visit the skate park, where Max hopes to see his crush, Brixlee, played by [Millie Davis](../actor/millie-davis). They are quickly approached by Atticus, a popular and boastful kid, played by [Chance Hurstfield](../actor/chance-hurstfield). Atticus takes them to a hidden spot in the park where he offers them a sip from a beer bottle. Despite bragging about how much he drinks, Thor hesitates and is mockingly nicknamed “Sippy Cup” by Atticus, highlighting the social pressures and peer mocking present during childhood.
Lucas, meanwhile, returns home to his parents, [Retta](../actor/retta) and [Lil Rel Howery](../actor/lil-rel-howery), only to discover that they are getting a divorce. This upsetting news weighs on him, though he keeps his feelings bottled up. At school, Max notices Lucas is troubled but chooses not to share his own concerns about his family troubles. Thor considers signing up for an upcoming school performance of "Rock of Ages" but backs out after Atticus dismisses singing as something only "try-hards" do.
At lunch, Max is approached by a popular boy named Soren, played by [Izaac Wang](../actor/izaac-wang), who invites him to a “kissing party” filled with girls—including Brixlee. Max hopes to involve Thor and Lucas, but Soren dismisses them as “too random,” sparking Max’s determination to prepare for the event. The boys, eager to learn about kissing, turn to inappropriate sources, watching porn and practicing on a sex doll they mistake for CPR training, showcasing their innocence and curiosity.
The boys also spy on Hannah—played by [Molly Gordon](../actor/molly-gordon)—and her friend Lily, using Max’s dad’s drone. They observe Hannah’s on-again, off-again boyfriend Benji—played by [Josh Caras](../actor/josh-caras)—delivering drugs and being put in the friend zone. When the girls discover the boys spying on them, they confront them and refuse to return the drone, leading to a chaotic chase.
Back home, the boys attempt to retrieve a rare baseball card from Thor’s parents’ closet, roping in a seller, Claude, played by [Stephen Merchant](../actor/stephen-merchant), who initially seems suspicious but turns out harmless. They also stumble upon and sell sex toys, jokingly claiming one is Thor’s mom, which fetches them some cash. With the money, they go to the mall but are pursued by Hannah and Lily, who have tracked their movements after their drone was stolen. A series of frantic events ensues, including Lucas crashing his bike and dislocating his arm, after which Max bravely distracts a pursuing Lily and helps Lucas.
Their adventure continues at a convenience store where they’re caught trying to smuggle beer and drugs by Officer Sacks, played by [Sam Richardson](../actor/sam-richardson). The boys, panicked, hid the evidence with Thor’s parents’ sex toys, leading to more chaos. They then attempt to cross a busy highway to reach the mall but narrowly escape danger as traffic speeds up, illustrating their reckless but courageous spirit.
The boys finally meet the girls in a tunnel, revealing they do not possess the drugs. Instead, they plan to buy them at Benji’s frat house, under the girls’ instruction, leading to a wild and paintball-filled confrontation with frat brothers. Despite the chaos, they manage to retrieve the drugs and escape.
As the story approaches its climax, Max rushes home to find his dad returning early. He sneaks in with the drone, accidentally making a mess in his father’s office, which results in a grounding. As conflicts and feelings surface, Max feels excluded when Soren invites only him to a party, prompting introspection among the trio.
In a heartfelt moment, Max, Thor, and Lucas confront their fears and insecurities. Max gains the courage to ask Brixlee for a kiss, which she accepts, giving him his first romantic experience. Meanwhile, Thor’s passion for singing shines through when he auditions for "Rock of Ages" despite the timing being tight. His persistence pays off when he lands a major role, and over time, he flourishes, gaining confidence and respect from his friends and family.
Lucas finds purpose by joining the school’s anti-bullying group SCAB, inspired by his experiences and desire to help others. Max faces heartbreak after losing Brixlee but finds solace in new friendships and relationships. The story concludes with a celebratory party, where the friends share meaningful moments together, reaffirming their friendship despite the ups and downs they faced.
In the end, they bond over a giant swing, relishing their youth and the unforgettable experiences of their middle school days, even joking that their parents’ private moments happen right where they played. Through humor, challenges, and friendship, What's After the Movie is a heartfelt look at growing up, addressing family issues, friendship, and finding one’s own voice amidst chaos.
