Private investigator Mitchell King is involved with two difficult cases. He fights to shield a female astronaut from a sexual harassment when he’s asked to persuade the stalker to quit. Mitch then becomes personally involved with the sexy murder witness whom he’s hired to protect. The investigations take Mitch from the refined engineering of space exploration to the squalor of biker bars and heroin shooting galleries. As he obsesses over his clients, Mitch stubbornly refuses to face his own shortcomings, and this threatens to drag him into a deadly encounter with a stone killer.
