The Sinner: Season 1 English TV Series

Season 1 of the drama series opens with Cora Tannetti (Jessica Biel), a young mother, stabbing a man to death with no apparent motive and without later being able to remember committing the crime. Detectives Harry Ambrose (Bill Pullman) and Dan Leroy (Dohn Norwood) are assigned to the case, but while Dan considers it open-and-shut due to several people witnessing the murder, Harry is convinced there must be something more going on and decides to continue the investigation on his own.
