Based on George Pendle's 2006 book of the same name, Strange Angel explores the dramatic intersection between genius and madness, science and science fiction. The story follows the life of Jack Parsons, a mysterious and brilliant man in 1940s Los Angeles, who by day helps birth the entirely unknown discipline of American rocketry, and by night is a performer of sex magic rituals and a disciple to occultist Aleister Crowley.
