After five months of bitter separation, Frank and Ginny Merritt are together again. Frank has found a promising new assignment at Rosewood, a posh psychiatric clinic. He installs Ginny and the children in a huge glass house near the sanitorium and immerses himself in the problems of his wealthy and celebrated patients.
Before long, Ginny's enthusiasm about her new home begins to wane. She is alarmed to notice that Bobby, her six-year-old, is becoming more withdrawn each passing day. Then she sees one of Frank's patients -- a famous movie star -- wandering nude on the outskirts of town.
When she tells Frank about the escape, he insists that she is hallucinating. Suddenly, Ginny feels cornered, alone. But she could not know the real danger; she is still unaware of the chilling truth about Rosewood.
