Schmidt and Jenko barely made it through high school the first time. Thanks to police program called 21 Jump Street, they went back a second time. The officers went undercover as high school students and made the school safe by taking down a huge drug operation. Since the program was so successful, more funding was made available and the operation moved across the street to 22 Jump Street. Schmidt and Jenko have been assigned to go to college. The guys get their own dorm, play college sports (well, kind of), and they get to party (they are college students, right?) all while investigating illegal drug activity.
