About the Show
Watch The Sinner from the beginning now on SHOWCASE ON DEMAND. Available through May 2, 2018.
Starring and executive produced by Jessica Biel, THE SINNER follows a young mother who, when overcome by an inexplicable fit of rage, commits a startling act of violence and to her horror, has no idea why. Detective Harry Ambrose (Bill Pullman) finds himself obsessed with uncovering the woman’s buried motive.
Based on Petra Hammesfahr’s book of the same name, the eight-episode crime thriller’s driving force is not the “who” or the “what” — but the “why.”
