Tweet Cute

Pepper Evans is a high-achieving senior at Stone Hall Academy, an elite Manhattan private school. Originally from Nashville, she moved to New York four years earlier when her mother became CEO of Big League Burger (BLB), a fast-food chain her parents co-founded. Her parents divorced amicably, and her father stayed in Nashville. Pepper's older sister, Paige, followed them to New York but developed a rift with their mother over the upheaval and now barely speaks to her from college at UPenn. Pepper captains the swim team, earns top grades, and secretly runs BLB's corporate Twitter account, crafting the snarky, viral-style tweets her mother relies on.

Jack Campbell, Pepper's classmate and the identical twin of Ethan, Stone Hall's popular student council president, lives above Girl Cheesing, a beloved East Village deli his family has operated since 1963. Privately, Jack has taught himself app development and secretly created Weazel, an anonymous chat app for Stone Hall students that assigns random animal usernames. He monitors it to prevent cyberbullying and has been messaging for months with a user called Bluebird, a fellow outsider whose identity remains hidden because Jack has disabled the app's reveal feature for their conversation. Bluebird is Pepper, though neither knows the other's identity yet.

The central conflict ignites when BLB launches new grilled cheeses, one of which copies the name and recipe of Girl Cheesing's iconic sandwich, created by Jack's grandmother, Grandma Belly. Furious, Jack tweets a comparison from the deli's small account. The tweet goes viral after Marigold, a pop star and deli regular with millions of followers, retweets it. Pepper's mother pressures her to fire back from BLB's account, and Pepper reluctantly does, despite her reservations about a corporate giant attacking a small deli.

A scheduling conflict forces the swim and dive teams to share pool lanes, pushing Pepper and Jack into weekly meetings. At one such meeting, Jack spots a drafted BLB tweet on Pepper's phone and realizes her family owns the company. He confronts her angrily, revealing the deli is his family's livelihood. Pepper is stunned and apologetic. The next morning, she delivers homemade So Sorry Blondies, a recipe with emotional significance from the early days of her parents' divorce. Jack concedes he overreacted and admits the viral attention has helped the deli's struggling finances. They strike a pact: The Twitter war will continue, nothing will be taken personally, and neither will hold back.

Over the following weeks, the war escalates. They trade increasingly creative tweets, and a YouTuber chronicles the feud in a popular vlog, dubbing it #BigCheese. Girl Cheesing's follower count skyrockets, and the deli installs a ticketing system to manage crowds. Through pranks and weekly meetings, Pepper and Jack grow closer, sharing baked goods, personal stories, and an easy banter that surprises them both. Pepper also forms a genuine friendship with Pooja, a longtime academic rival.

Pepper proposes a retweet showdown through Hub Seed, a major media outlet: Both accounts will submit unidentified grilled cheese photos, and whichever gets more retweets wins. Jack adds a personal wager involving Pepper jumping off the high dive, a fear she has carried since freshman year. Ethan secretly swaps in a photo of himself holding the grilled cheese, which goes viral and gives Girl Cheesing an unfair advantage. Jack is furious, and the long-simmering tension between the twins over Ethan's perceived golden-child status erupts.

Their bond deepens off Twitter. When Pepper schedules her Columbia admissions interview at the wrong location, Jack rides the bus with her to campus, a significant moment as she has never navigated the city alone. On the ride, they share personal stories about their families. That evening, Pepper tells Jack she thinks he hides behind his class clown persona, an observation that deeply affects him. Meanwhile, on Weazel, Bluebird sends Wolf a link to P&P Bake, the anonymous baking blog she runs with Paige. Jack recognizes Pepper's distinctive recipes and realizes Bluebird is Pepper. He is elated but paralyzed: He knows Pepper suspects Wolf is Landon, a handsome classmate, and cannot bring himself to reveal the truth. Bluebird and Wolf agree to reveal themselves on Senior Skip Day.

Jack coaches Pepper through jumping off the high dive, and after a playful splash fight, they end up face-to-face in the shallow end with an unmistakable romantic charge. Landon interrupts, and Jack withdraws, visibly hurt when Pepper mentions she and Landon text on Weazel. On Senior Skip Day, Pepper confirms Landon is not Wolf. She becomes violently ill from a street vendor's hot dog, and Jack arrives to help, walking her home without revealing the truth.

Pepper visits the deli to bake for a school bake sale, taking the subway downtown alone for the first time. They bake together for hours, and Jack's mother warmly welcomes her. Watching Mean Girls on the couch, they finally kiss. Jack pulls back, intending to confess about Weazel, but Pepper's mother bursts in with Jack's father, ordering Pepper to leave. After they depart, Grandma Belly falls and is hospitalized with a concussion.

Events spiral. A Hub Seed article outs Pepper and Jack by name as the teens behind the Twitter war. Pepper's mother tweets a jab at Girl Cheesing without Pepper's knowledge. Ethan, using Jack's phone via Face ID, finds a photo of Pepper vomiting on Senior Skip Day and tweets it from Girl Cheesing's account, creating a viral meme. Then Pepper overhears Jack telling a friend that discovering Bluebird's identity made everything complicated and that he wished he had not known. She realizes Jack is Wolf and feels devastated. In her shock, she blurts out that Jack made Weazel within earshot of Vice Principal Rucker. After a classmate is cyberbullied on the platform, Jack confesses to the administration. Pepper is suspended for two days; Jack for a week.

During her suspension, Pepper's mother reveals the full history. She once worked at Girl Cheesing during a summer romance with Jack's father, Sam, developing recipes Sam later claimed as his own, destroying her dream of opening her own café. The grilled cheese copycat was her deliberate retaliation, not a corporate accident. Pepper also reconciles with Paige, who reveals she moved to New York to protect 14-year-old Pepper, not out of spite. Pepper and her mother bake together and travel to Philadelphia to visit Paige. Meanwhile, Jack tells his father he wants to pursue app development rather than inherit the deli. His father responds with pride, revealing that Ethan also feels inadequate, believing Jack is the favored twin because the family trusts him with the business.

Pepper spends a day of her suspension working the register at Girl Cheesing. Over lunch in Washington Square Park, she and Jack lay everything out. Jack apologizes for lying about Weazel and for the meme; Pepper apologizes for nearly exposing him. Jack asks if they can leave Twitter, Weazel, and their parents' baggage behind. Pepper says she does not want to start over but wants to continue from where they are. They kiss without interruption. In an epilogue one year later, Jack studies app development at NYU while interning at BLB, and Pepper studies business management at Columbia while working at Girl Cheesing, where she has added her desserts to the menu. Paige comes home regularly, the family rift mended. The deli's newest menu item is the PepperJack Grilled Cheese.
