In the prehistoric past, a young man struggles to return home after being separated from his tribe during a buffalo hunt. He finds a similarly lost wolf companion and starts a friendship that would change humanity.

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.
