In San Francisco, a psychopathic gangster and his mentor retrieve heroin packages carried by unsuspecting travelers.
Leave it to Don Siegel to turn a regular police investigation story into a tough, tense thriller skillfully photographed on real locations with a highly suspenseful ending.
Halliwell*: "Energetic, polished movie version of a popular TV series, San Francisco Beat."
Maltin**1/2: "Cult favorite with fans of director Siegel, despite the fact that it's a pretty ordinary police procedural."
