S2·E5 The Convoy

The U.S. Cavalry is turning over a Gatling Gun to the Canadian Mounted Police, but when Clive arrives to escort the wagon into town, he is shot by one of the Mountie impersonators who has already killed the Mounties assigned to the transport. When they arrive in Bordertown to assume possession of the gun, Jack becomes suspicious of their behavior, and arrests one of them when he becomes aggressive with Marie. The next morning, the ""Mounties"" take the gun, and leave Bordertown. Meanwhile, Couteau has found the wounded Clive, and reports it to Jack, who must find a way to recover the stolen gun.
