 While Rosco is chasing the Dukes, a pair of bank robbers runs the sheriff s car off the road. After the car sinks into the lake, the robbers kidnap Rosco. While the town grieves over Rosco s apparent fate, the robbers are plotting their next move: unveiling a third associate, a vicious crook named Woody - who looks exactly like Rosco! Their ultimate scheme is to rob an armored car that is scheduled to arrive at Hazzard Bank. When Bo and Luke expose the phony Rosco, Woody and his associates imprison the Duke cousins at their hideout (along with the real Rosco) so they cannot interfere in their plans.
