Novelist Geoff (Cockrell) and his wife Sally (Adams) rent an isolated countryside bungalow to enable Geoff to finish his latest book without the distractions of life in London. On their arrival, they are horrified to find a dead man in the property; before they can report the discovery they are confronted by Duke (Payne), a gangland boss, and his henchmen who have, it transpires, been using the empty property as a hide-out for stolen valuables which they are planning to smuggle out of the country. A rival gangster, Juan (Derek Sydney), also has his eye on the goods and has discovered their whereabouts. The dead man is one of his minions.
