Susan Scott and Simón Andreu star in this thriller directed by Luciano Ercoli. When nightclub dancer Nicole Rochard (Scott) is questioned by police in Paris as to the whereabouts of some diamonds suspected to have been stolen by her father, she is unable to give them any information. Shortly after, Nicole is stalked by a balaclava-wearing man with distinctive blue eyes who is certain she knows more about the diamonds than she is letting on. Fearing for her safety, Nicole flees to England, only to find her life in peril once again soon after she arrives. The cast also includes Frank Wolff and Carlo Gentili.
