Gil's old pal Piney schemes to rob a bank and join Gil's drive to cover his mob's escape. City bankers foreclosed on Piney's huge ranch after it was decimated, so he dreams of rehabbing it via their vault. As a life-long resident of Republican Collin County, Piney knows of old mining tunnels under the town, so he teams with the Rose Gang to tunnel to the bank, from a nearby hotel. Under the guise of recuperating from a broken leg on the inn's ground floor, the respected cattleman fakes a closed, never-ending card game.
