en CB01 OFFICIAL. In Los Angeles, black motorcycle police officer Mark Johnson patrols gang-infested neighborhoods with his white partner and best friend, Jeff McMillan. One afternoon, Mark has a run-in with a gang known as The Virgins, whose leader, Big Donnie, is taken aback by the policeman's understanding, dignified demeanor despite the gang's constant derision. When Mark advises Donnie not to continue to allow his heavily pregnant girl friend, Judy, to ride a motorbike, the gang leader agrees. Later, after Donnie actively seeks Mark out for advice, the Virgins' second-in-command, Kenny, reacts with outrage.
