San Francisco, 1967. Kim, a young detective fresh out of police academy, teams up with Ulysses Ford, a jaded cop at the end of his career, and finds herself investigating a series of brutal murders connected with satanism, as the two of them plunge into a maelstrom of black masses and satanic rites… A thriller loosely based on the story of Anton LaVey, the controversial Frisco citizen who founded the Church of Satan, that reveals the Summer of Love also to have been a “summer of hate.”
