The U.S. Military offers Jack, Richard and the Aerojet team a classified mission that could turn the tide of World War II, but which comes with increased scrutiny of Jack's personal life. As Jack strives to straddle the worlds of mysticism and science, Virgil Byrne's crusade against the Agape Lodge forces Jack and Susan to offer the cult safe haven in their Pasadena mansion, only to have their lives further disrupted by the return of Ernest Donovan, who has come back to Los Angeles more broken than ever.
Jack Parsons is a brilliant and ambitious blue-collar worker of 1930s Los Angeles who started as a janitor at a chemical factory but had fantastical dreams that led him to birth the unknown discipline of American rocketry.
Along the way, he fell into a mysterious world that included sex magic rituals at night, and he became a disciple of occultist Aleister Crowley. Parsons used Crowley's teachings of self-actualization to support his unimaginable and unprecedented endeavor to the stars.
