Jack's expert witness testimony at a high profile trial thrusts the rocketry team into the spotlight and helps land them a coveted invitation to The Athenaeum. Meanwhile, Virgil drops off Patty, Susan's rebellious teenage sister, for a disruptive weekend stay, and Ernest's wife, Maggie, makes a surprise return. When Jack's evening at The Athenaeum doesn't go as planned, Jack seeks out Ernest to blow off some steam and ends up on a dark detour into the Los Angeles underbelly.
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.
