Screenwriter:Raymond de Felitta
The film is based on the eponymous novel by novelist Frank De Felitta. The book is described as follows: "Tracey and Phil are lovers. They have planned a romantic cruise as the perfect ending to a perfect affair. But the Penny Dreadful, the yacht on which they have chosen to sail, was never intended for pleasure. Nor are Catain and Mrs McCracken the pleasant, middle-aged couple they seem. Soon the accidents begin: a series of accidents. And then the chores and deprivations in an ever-tihtening chain of punishments and hardships. It is as though they have embarked on a passage through fire, a cruise through hell. Tracey Hansen and Philip Sobel are about to be initiated into the rites and ways of evil."
