Based on the Pretty Little Liars series of young adult novels by Sara Shepard, the series follows the lives of four girls — Spencer, Hanna, Aria, and Emily — whose clique falls apart after the disappearance of their queen bee, Alison. One year later, they begin receiving messages from someone using the name "A" who threatens to expose their secrets — including long-hidden ones they thought only Alison knew.
The Crains, a fractured family, confront haunting memories of their old home and the terrifying events that drove them from it.
A "contemporary prequel" to the 1960 film Psycho, depicting the life of Norman Bates and his mother Norma prior to the events portrayed in Hitchcock's film, albeit in a different fictional town and in a modern setting. The series begins after the death of Norma's husband, when she purchases a motel located in a coastal Oregon town so she and Norman can start a new life.
When a young boy vanishes, a small town uncovers a mystery involving secret experiments, terrifying supernatural forces, and one strange little girl.
