In a luxurious seaside villa, a modest young woman finds herself in the company of a strange family: an unknown and wealthy father, his extravagant wife, his daughter, an ambitious woman, a rebellious teenager, and their creepy maid. Someone is lying. Between suspicions and lies, a mystery grows and the evil spreads.

Constance, a 40-years-old real estate agent, gets fired from her job. With no options left, she contacts her former boss, from the small agency where she started her career. To her surprise, he is hiring, but explains he may have already found someone. Constance is convinced she will get the job because of her experience and extensive qualifications. But when Audrey, a younger and prettier woman, is hired instead, it proves too much for Constance to take.
