While on the beat one evening PC Dave Hollis (Barry Foster) came across beautiful German girl Lisa Shillack (Margit Saad) locked out of her flat. He helps her and before long the pair have fallen into an affair. Dave learns that Lisa's husband Simon Shillack (George Pravda) is a rich businessman that she has little love for and that she wants rid of. Before long Lisa is scheming to have him murdered and begins to slowly charm and coerce Dave into undertaking the murder.
Margit Saad is a femme fatale in the classic mode, easily seducing the naive young PC Hollis, while the stylish black and white camerawork enhances the classic noir feel of the piece. Barry Foster is excellent as the naive Bobby ( policeman on the beat) who gets suckered into murdering Saad's husband for insurance - definitely a far cry from Van Der Valk. It's a taut, fast-paced thriller that just sucks you into its tale.
