21 Jump Street revolves around a group of young cops who would use their youthful appearance to go undercover and solve crimes involving teenagers and young adults.

When cops Schmidt and Jenko join the secret Jump Street unit, they use their youthful appearances to go undercover as high school students. They trade in their guns and badges for backpacks, and set out to shut down a dangerous drug ring. But, as time goes on, Schmidt and Jenko discover that high school is nothing like it was just a few years earlier -- and, what's more, they must again confront the teenage terror and anxiety they thought they had left behind.
