Plot

Morton Schmidt (Jonah Hill) and Greg Jenko (Channing Tatum) are former classmates who meet again at police academy. Schmidt was a nerd while Jenko was a jock. They end up becoming friends at the academy as they help with each others' weaknesses, with Schmidt helping Jenko study and Jenko motivating Schmidt through physical activity. They graduate together as partners, but are assigned to park patrol. They catch a break when they spot a group of drug dealers and arrest their leader Domingo (DeRay Davis). However, the department is forced to release him as Jenko forgot the wording of the Miranda rights. The two are reassigned to a revived specialty division on 21 Jump Street.

They are introduced to Captain Dickson (Ice Cube), who explains the division specializes in infiltrating high schools and that they were chosen because of their youthful appearances. Schmidt and Jenko are assigned to go back to their old high school to stop a new synthetic drug from spreading to other campuses by finding the supplier. They go undercover as brothers, living at Schmidt's parents' house, and see that their high school has changed. Jenko accidentally switches their identities and they get each others' classes. They learn the lead dealer of the drug is the popular Eric (Dave Franco), but he is not the supplier.

They go to the dealing room where Eric forces them to take the drug there and not wait. They attempt to regurgitate it but are unsuccessful, and they undergo the phases of the drug while talking to their P.E. teacher, Mr. Walters (Rob Riggle), and also while running track and during band practice. The mistakes that happen at the track meet causes Eric to take a liking to Schmidt.

Schmidt manages to fit in with the popular kids and takes a romantic interest in Eric's friend Molly (Brie Larson), while Jenko becomes friends with the nerds in his AP Chemistry class while his teacher Ms. Griggs (Ellie Kemper) takes a sexual interest in him. Jenko discovers that his new friends secretly tap into other people's cell phones to listen into their conversations. Schmidt decides to throw a party at his house to gain Eric's complete trust and Jenko takes the opportunity to tap into Eric's phone. Despite Captain Dickson ordering them not to serve alcohol and drugs to minors, they nevertheless buy alcohol and steal confiscated marijuana. When Eric arrives with Molly and his other friends, Jenko steals Eric's phone for his friends to tap into while Schmidt fights off a rival of Eric's.
