A bunch of rap-star wannabes attempt gangsta rap effrontery, call themselves CB4 (referring to a prison cell block), and become all the rage in the tough-as-you-can-be rap music industry. Before long, however, they discover themselves to be the targets of real gangsta violence. This parody featuring Chris Rock, Allen Payne and Deezer D, contains nudity, profanity, violence, substance abuse and sexual situations--as all gangsta rap comedies should.
