Millions of single women rent apartments. They do not think about who lived there before them. They do not know the owners. They do not think about changing the lock. After separating from her husband, a young doctor Juliet Dermer begins a new life in a spacious rented loft. The cheap apartment is so good that Julia can not believe her luck. Soon, however, she begins to suspect that she's not alone there. With horror, she realizes that the lovely landlord Max chose her for his manic game of cats and mice.
