Junior constantly flirts with her father, while Billy keeps his incestuous urges to himself despite his wife pointing out his obvious attraction to her.
Billy's marriage to Sheree is loveless as he could not leave her due to his reliance on her starring in his films, often turning to his lust for his daughter in writing erotic scripts.
Sheree arrives home and catches her husband and their daughter on the verge of sex, and she forcefully pulls out Junior, who flees to her room.
The next morning, Lou Jean arrives and she and Sheree find that Junior has fled home, informing Billy of her disappearance.
Junior declares that, having been ultimately rejected by her father, she had moved in with Sir Harry as his new lover and is at home to pick up her valuables before she bids her parents farewell.
With Junior no longer needing assistance, Lou Jean leaves as well, having realized being lovers with both Billy and Sheree has been too much for her.
