Morton Schmidt (Jonah Hill) and Greg Janko (Channing Tatum)
occupy different rungs of the social ladder at their High School. Greg is a popular jock, and Morton is unpopular
nerd. Years after graduation, their
paths cross again at the local police academy.
Morton has the brains, and Greg has the brawn. Finding that they complement
each other nicely, a bond grows between the two. Unfortunately their performance leaves a lot
to be desired. In hopes of salvaging
their careers, a superior decides to assign them to 21 Jump Street, where they
will serve under the belligerent Captain Dickson (Ice Cube). They are then required go deep cover as high
school students to infiltrate a drug ring operating out of their old alma mater. To their chagrin, high school turns out to be
even more of a challenge the second time around.
