Lauren Monroe (Lily Collins) is a rising young New York City District Attorney and the successful daughter of a powerful New York family steeped in old-money wealth and privilege. When her father (Patrick Warburton) suddenly dies, she is given a set of keys to an unknown bomb shelter on their estate as her inheritance instead of access to the family fortune. There she discovers a secret buried so deep that not even her mother (Connie Nielsen) knew about it... a man barely alive (Simon Pegg), locked and chained in captivity for years on the grounds of their estate. Lauren makes the fateful decision to keep the discovery a secret in the hope that she can uncover the truth while managing her own life and her brother's impending election campaign and avoid destroying her family name. Entrapped in a web of lies and manipulation, what she discovers may rip apart the very fabric of her family dynasty and threaten her life and all those around her.
