Down on her luck and on the verge of eviction, Ann Foster lands a job as a wealthy widow's personal assistant. It's a live-in role that provides her with a place to stay in the guest house, and the job pays well. It seems like a wonderful opportunity, but Ann discovers a locked room in the guest house, and this begins to arouse her suspicions. As a secret past begins to slowly reveal itself, Ann tries to fit the pieces together. With the unsettling behavior of the other employees who work on the property and the mounting evidence that something terrible happened in the guest house, Ann soon discovers that what she has gotten herself into is far from a perfect arrangement.
