Frederic Goode directs this 1960s British thriller starring Trisha Noble as a femme fatale. When Francesca (Noble) and her lover Joe (Shaun Curry) kill a wealthy man for his fortune they believe they have committed a carefully crafted crime they'll get away with. However, unbeknown to them, their victim's business partner Malo (William Dexter) is aware of their misdeed and seeks to turn it to his advantage. Complicating matters further is the involvement of Dennis Parbury (Mark Burns), an agent who arrives on the sun-drenched Mediterranean island to investigate Malo and his associates for drug smuggling. Will Parbury stumble across the murder plot, too?
