When his girlfriend is murdered in Golden Gate Park, Mark (Don Mitchell) is bound and determined to take the law in his own hands to catch the killer. As a result, Mark is himself held for murder when the chief suspect turns up dead. In his efforts to clear, Mark, Ironside (Raymond Burr) instills in his hotheaded associate a new and daunting respect for "due process." Former Dobie Gillis star Dwayne Hickman turns up in a supporting role, as does future Kung Fu and Kill Bill leading man David Carradine. ~ Hal Erickson, Rovi
