Recovering PI Steve Brice is taking long walks down short halls when he is invited to Tobago by his old pal Harry Harriman. He anticipates laconic days and maybe an undulant lady, until Harry’s wife is murdered. After his pal is arrested for the crime, Brice must work fast to find the killer before the cops move Harry to a prison known for rapes, and fondly nicknamed the Mortuary. Navigating bikinied tourists and tough rum shops, Brice enlists a green-eyed Watson with hair-pin curves to help save his friend. Meanwhile, the man who murdered Brice’s sister 17 years ago is finally scheduled for execution, and Brice may have to choose between witnessing justice for her and saving his pal.
