21 Jump Street

21 Jump Street movie synopsis:  In the action-comedy 21 Jump Street, Schmidt (Jonah Hill) and Jenko (Channing Tatum) are more than ready to leave their adolescent problems behind. Joining the police force and the secret Jump Street unit, they use their youthful appearances to go undercover in a local high school  in order to bust a drug ring. But they find that high school is nothing like they left it just a few years earlier - and neither expects that they will have to confront the terror and anxiety of being a teenager again and all the issues they thought they had left behind.
