After discovering the body of murdered female Chinese agent Mai Ling (Jeanne Roland) in their trendy Soho (London) nightclub, groovy owners Charles Salt (Sammy Davis Jr) and Christopher Pepper (Peter Lawford) partake in a fumbling investigation and uncover an evil plot to overthrow the government.
Despite continual interference from the law, the duo manages to uncover a plot to take over the country using stolen nuclear submarine, HMS Hercules.
Davis and Lawford are backed by an excellent British cast including Michael Bates as the incompetent Inspector Crabbe, Ernest Clark as Colonel Balsam, and John LeMesurier as eyepatch-wearing villain Colonel Woodstock.
Some of the action is surprisingly violent for a lightweight comedy. A sequel, One More Time (1970) – directed by comedian Jerry Lewis – was an unmitigated disaster.
