The official word on City of Angels reads:

A spiritual descendant of the original Penny Dreadful story set in Victorian-era London, “Penny Dreadful: City of Angels” opens in 1938 Los Angeles, a time and place deeply infused with social and political tension. When a grisly murder shocks the city, Detective Tiago Vega is embroiled in an epic story that reflects the rich history of Los Angeles: from the building of the city’s first freeways and its deep traditions of Mexican-American folklore, to the dangerous espionage actions of the Third Reich and the rise of radio evangelism. Before long, Tiago and his family are grappling with powerful forces that threaten to tear them apart.

“Penny Dreadful: City of Angels” explores an exciting mix of the supernatural and the combustible reality of the period, creating new occult myths and moral dilemmas within a genuine historical backdrop. This chapter is a bold new vision that will employ all new characters and storylines.

Penny Dreadful’s John Logan is writing and serving as showrunner on Penny Dreadful: City of Angels.
