Reborn into a new life, Leon enters Stanford and forms the "504 Apartment" foursome with Danny, Paroo, and Cross. Armed with memories of his past life, he invests in the failing Blue Bull Steakhouse—yet details like a California license plate reading 00001 and his private wine collection lead others to assume his background runs unfathomably deep. As the Paroo family probes the 504 crew, Danny's Hunter family heritage and the hidden forces behind Cross's mother are exposed in turn—while Leon, seemingly the most ordinary of them all, becomes the one mystery that even the mightiest families dare not touch.
