Two new police officers take on an undercover job of busting a high school drug ring; two police officers go undercover on a college campus to stop a suspected drug-trafficking ring. 21 Jump Street When cops Schmidt (Jonah Hill) and Jenko (Channing Tatum) join the secret Jump Street unit, they use their youthful appearances to go under cover 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. 22 Jump Street Although they made their way through high school successfully, an investigation at a local college brings big changes for undercover officers Jenko (Channing Tatum) and Schmidt (Jonah Hill). When Jenko meets a kindred spirit on the football team and Schmidt infiltrates the bohemian art-major scene, both men begin to question their partnership. Not only do they have to crack the case, but now the two overgrown adolescents must learn how to behave like adults.
