Jack Winter is an abusive man who exploits and beats women. One night, after a quarrel with a man whose gamekeeper he was, Jack is found dead, shot from his own gun. Soon after that, Jack's widow runs away, catching a train, and disappears, becoming the main suspect. While the police unsuccessfully investigate the murder and search for a suspect, a mysterious woman appears at the Davenant Priory. Weak sighted Sir Oswald doesn't notice anything suspicious, but there is something strange about Miss Martin and she can't hide the secret forever.
