Each season of The Sinner finds Detective Harry Ambrose (Bill Pullman) investigating the unlikely culprits of various crimes. Season 1 finds him trying to uncover the truth of why Cora Tannetti (Jessica Biel), a mild-mannered mother, stabbed a man to death in an apparently random act of violence, while Season 2 sends him back to his upstate New York hometown to look into the case of a young boy who claims to have poisoned his parents. Ambrose’s own deep-seated trauma helps him relate to the people he’s investigating, which subsequently helps him deduce their true motives, making for a mystery that’s less of a who dunit and more of a why dunit.
