At the start of 21 Jump Street, Schmidt (Jonah Hill) and Jenko (Channing Tatum) fill the stereotypical high school roles, one a chubby nerd who can't get a date for the prom, and the other a gorgeous but dumb jock barely able to graduate. Once out of high school, they're anxious and ready to leave all the teenage angst behind, so they both join the police force where they become unlikely friends, each making up for the other's weakness. Now police officers who have severely (and riotously) fouled up a potential drug bust during their bicycle-riding park duty, they are assigned to a revamped secret unit where they'll use their youthful appearance to go undercover at a local high school to infiltrate the sellers in a drug ring responsible for the death of one teen, in order to catch the provider before the drug hits the streets and spreads to other schools. Things go wrong from the get go, when the roles assigned by their Captain are inadvertently switched and Schmidt ends up in track and drama hanging out with the cool kids, and Jenko instead ends up in AP chemistry with the nerds. They'll both have to face old and new fears alike in order to crack the case.
The best description for this movie is rude, crude and Hilarious (with a capital H). I haven't laughed so much in a long time. On par with another famous Hill comedy, Superbad, 21 Jump Street has something for everyone, the youngsters looking for raunch and action, as well as the old fans of the original 80's TV show. Oh, and lest you think it's all raunchy humor and foul language, let me tell you the movie has tons of heart, offering a heartwarming buddy story which tugs at your heart strings as much as the comedy tickles your funny bone.
