On the run from the police, thieves stumble upon an abandoned mansion on a deserted island.
Production.
The film was made by a new company, Absorbing Films, which had been set up by Michael Eaton-Eland, a prominent London figure, who wanted to move into filmmaking. Filming started in December 1965 on the isle of Capri. It was Martine Carol's first movie in three years. It was one of a number of films Steel made in Europe. 
The film was shot in Italy and Yugoslavia. However several of the actors and technicians claimed they had not been paid. Filming came to a halt. Carole married Eaton-Eland in June 1966, at which stage the film had not been completed.
Carol died of a heart attack in February 1967. Production resumed under another director.
Reception.
The "Monthly Film Bulletin" criticised its "nonsensical story".
