The story (based on a novel by James Hadley Chase) concerns the efforts of the genial and deceptively tentative Lepski (Michael Brandon), an insurance company detective, to track down a valuable medieval Russian icon, which was stolen by Bradley (David Carradine), a master thief.

Alex and his sister run a business designed to break up relationships. They are hired by a rich man to break up the wedding of his daughter. The only problem is that they only have one week to do so.
