The death of his grandmother brings Nikos Kotsikas from New York to England to join his father, Leon, and meet his stepmother, Cathy, for the first time. Bereft and unhappy, overshadowed by the flamboyant and successful Leon, he is drawn to his father's wife from the first and she to him. Neither sees the danger of the attraction until it is too late to escape the web of lies and deception in which they are inevitably ensnared. When Cathy's son Adam, a compulsive gambler, discovers their secret, it leads to blackmail, betrayal, and finally to murder on a sunlit Greek mountainside.
