A food bank deliveryman is found buried, up to his neck, in the backyard of a suburban home. What's even more bizarre than the way in which he was buried is the fact that flower petals were placed around his head and from a distance the victim looks like a large flower. The unusual circumstances of his death lead Crews and Reese to believe the murder may be connected to a cult from the 70s. Meanwhile, Crews defies the FBI's warning and confronts Mickey Rayborn about his role in the conspiracy that put Crews in jail.
