21 Jump Street revolved around a group of young cops who would use their youthful appearance to go undercover and solve crimes involving teenagers and young adults.
Dennis Booker who once worked for the LAPD is now hired by the US office of a large Japanese Company to investigate some suspicious insurance claims. He hates authority and being told what to do, he even goes on his own missions to benefit his friends and family, not the government. Booker ran alongside season 4 of 21 Jump Street and is a spin-off of 21 Jump Street
In 2005, scholarly student Morton Schmidt (Jonah Hill) and popular underachieving jock Greg Jenko (Channing Tatum) miss their school prom; Schmidt being rejected by the girl he asked to be his date and Jenko being barred from attending because of his grades. Seven years later, the duo meets again at the Police Academy and become friends and partners on bicycle patrol. They catch a break when they arrest Domingo (DeRay Davis), the leader of a Outlaw motorcycle club motorcycle gang, but are forced to release him after they failed to read him his Miranda warning.
Two years following their success in the 21 Jump Street program, Schmidt (Jonah Hill) and Jenko (Channing Tatum) are back on the streets chasing narcotics. However, after failing in the pursuit of a group of drug dealers led by Ghost (Peter Stormare), Deputy Chief Hardy (Nick Offerman) puts the duo back on the program to work for Captain Dickson (Ice Cube) – now located across the street at 22 Jump Street. Their assignment is to go undercover as college students and locate the supplier of a drug known as "WHY-PHY" (Work Hard? Yes, Play Hard? Yes) that killed a student photographed buying it on campus from a dealer.
