Based on a real life experience, a couple Patty and Drake buy their dream house in San Francisco. They decide to rent out the ground floor apartment to help out with the mortgage payments. Charming Carter Hayes initially seems to be an ideal tenant, but after he moves in things begin to go wrong. He doesn't pay his rent, refuses to leave and barricades himself in. Landlord/Tenant Laws are strange, even in San Francisco and he couldn't be forced out. When he is tired of playing his psychological games, he leaves to find another victim. Patty goes after him and wants revenge.
