CB4

Chris Rock stars as Albert, a suburban wannabe rap star who, along with two friends, has tried everything to break into the music business. However, when Albert is mistakes for an undercover cop by a nasty thug named Murphy, he adopts the newly incarcerated Murphy's persona and christens his rap group CB4, after Murphy's cell block address. Vowing to glorify violence and disparage women, CB4 are quickly signed to a lucrative record contract. Soon, the band is selling out concerts, and attracts a nerdy documentary filmmaker (Elliott) to chronicle their rise to the top of the charts among the protests of outraged parents and politicians.
