Dr. Marcelo, a respected psychologist, finds himself in a taboo situation when his stepdaughter, Whitney, walks into his clinic. She's been exhibiting unusual behavior, and Marcelo, preoccupied with his own desires, sees an opportunity to fulfill his fantasies. He manipulates the situation, playing the role of the caring doctor to the hilt. Whitney, unsuspecting and trusting, follows his "treatments," which involve intimate examinations and "therapeutic" role-play. The line between professional and personal blurs as Marcelo's lust grows, with Sophia Locke, his other stepdaughter, unknowingly walking in on their inappropriate "session."
