Bill Pullman plays Detective Harry Ambrose in USA Network’s The Sinner, a police procedural in which his character investigates complex murders. Season 1 of the anthology series was inspired by Petra Hammesfahr’s novel of the same name, and opens with married mom Cora Tannetti (Jessica Biel) stabbing a man to death on the beach for seemingly no reason. As Ambrose digs into the case—and Cora’s past—horrific details about her past traumas begin to emerge. Three subsequent seasons followed, with each one based on a new crime.
