When 23 year old Cassandra Vale accepts her first job as an au pair, she finds herself placed with a wealthy family in a rural estate outside of Paris, and all seems too good to be true. But she soon discovers that behind the gilded gates lies a dysfunctional family, a twisted marriage, troubled children, and secrets too dark to air. Cassandra is convinced she's finally found a fresh start when she takes a job as an au pair in the idyllic French countryside. Just beyond the Paris city limits, the Dubois manor is a grand relic of the past, the family its picture-perfect occupants. It's the escape Cassandra needs-until she uncovers dark secrets that prove things aren't as glamorous as they seem. Beneath the opulence lies a dark web of malice, one Cassandra finds all too familiar, triggering dreams from her own violent and tortured past, one from which she desperately runs. And when a grisly murder tears the house apart, it threatens to take down her own fragile psyche with it.
