Nigel and Derek, two cousins who disliked each other since childhood, went on a boat trip ... with which only one of them returned - Nigel The police do not believe his misleading account of Derek's mysterious disappearance and believe that the young man is a murderer, ineptly trying to hide his crime.

Or still a cynical, calculated crime? But who from the motley company could have strong enough motives to get rid of the pretty and kind Worsley?..
