A small town is suddenly and inexplicably sealed off from the rest of the world by an enormous transparent dome. While military forces, the government and the media positioned outside of this surrounding barrier attempt to break it down, a small group of people inside attempt to figure out what the dome is, where it came from, and when (and if) it will go away.
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.
Set in the present, the series offers a bold, subversive take on Archie, Betty, Veronica and their friends, exploring the surreality of small-town life, the darkness and weirdness bubbling beneath Riverdale’s wholesome facade.
