On his way to Bordertown to assist Corporal Bennett in the delivery of a payroll wagon to Ft Walsh, a young Mountie is murdered by a gang who mistakenly believe he is carrying the payroll. Discovering their error, they assign their newest member the task of assuming the identity of the Mountie, and send him into Bordertown to join the escort. Clive leaves town with him and the payroll, unaware that he is being led into a trap.
