A repressed therapist falls into obsessive "bad love" with her ex-con patient, Jax. Upon his release, he claims her in one relentless day of depravity—rough domination, every hole used, squirting floods, piss rituals, fisting stretches, and taboo threesome with her 18-year-old stepson Tyler. Betrayal, humiliation, and breeding culminate in her being utterly "fucked to the core" just before her husband returns.
