Det. Murdoch investigates the shooting death of a New York City man on a Toronto streetcar. He was shot in the stomach but no one heard a shot. Back at the station, he's surprised to find his friend from Bristol, Anna Fulford, who has come to Toronto via New York city with her fiancé and are on their way to Niagara Falls to be married. He's vanished, however, and Anna is naturally worried. Soon after confirming that the dead man is not her fiancé, someone takes a shot at her. After making inquiries with the New York City police, Murdoch learns of a new kind of criminal organization known as the Black Hand. Insp. Brackeneid meanwhile is uncomfortable when his political backer orders him to get rid of a band of gypsies that are camping in the woods.
