Norman Bates (Anthony Perkins) is still running Bates Motel all alone and keeping the dressed skeleton of the killer from PSYCHO II. He meets three new people who come to the Motel: a beautiful young woman who has left the convent named Maureen (Diane Scarwid), a guitarist desperate for money named Duke (Jeff Fahey) and a nosy reporter named Tracy Venable (Roberta Maxwell), who is writing an article about serial killers being put back on the streets. As Norman and Maureen begin having a romantic relationship, someone dressed as Mother begins to kill people around the Motel one-by-one. Is Norman taking orders from Mother again, is Tracy trying too hard to prove that Norman is a viscous serial killer, or is there something much more than the obvious?
