Described as a spiritual descendant of the original “Penny Dreadful,” the new series opens in 1938 Los Angeles. When a grisly murder shocks the city, Detective Tiago Vega (Zovatto) is embroiled in a story that reflects the 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.
