A 1.ª temporada de Penny Dreadful: City of Angels estreou a 26 abril 2020.

When a grisly murder shocks Los Angeles in 1938, Detective Tiago Vega and his partner Lewis Michener become embroiled in an epic story that reflects the rich history of the city: 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.
