Charlie O'Rourke, a friend of Heyes and Curry from their outlaw days, is about to be hanged for a robbery which resulted in several deaths. He recognizes Heyes and Curry from his jail-cell window and offers them a map to the gold bars he stole, wanting that to be his "legacy" to them. The boys decline, but others -- a saloon singer and Bannerman detective Harry Briscoe -- hunting after the gold. In the interests of staying honest and turning the tables on Briscoe, an old foe who might be a friend, the boys reluctantly take part.
