At one of his LSD parties, Terry goes off with a black woman. Disappointed by his gigolo antics, Mrs. Golden cuts off Terry's subsidy. While Terry attempts a reconciliation with Mrs. Golden, Mr. Golden discovers them and is killed in a fight with Terry. The adulterers separate and, although the police believe Mr. Golden's death to be accidental, Mrs. Golden threatens to blackmail her lover. Terry resolves the situation by administering to his mistress a fatal overdose of narcotics. Terry later becomes a successful novelist. When the Goldens' daughter returns home from school, the writer seduces her. Afterwards, she slays him.
