Set in Radiant City, a dystopian municipality inspired by the Bauhaus and Fritz Lang’s Metropolis, the series concerned a mysterious figure who purported to be its architect.

Coven leader de Vries, trying to escape the wrath of a goddess, has his twittering acolyte suggest that they drive away. His line - 'Plymouth?
