Someone in the SFPD must go undercover with a group of Vietnam war resisters to ferret out a murderer. Given a choice between middle-aged Mike Stone (Karl Malden) and youthful, shaggy-haired Steve Keller (Michael Douglas), the authorities opt for Keller. Posing as an anti-war activist, Keller tries to find out who killed a rather notorious Marine deserter...and why. Featured in the cast are two actors who'd essayed villainous Streets of San Francisco roles in the past, Don Stroud and Michael Burns. ~ Hal Erickson, All Movie Guide
