Three outlaws arrive in the country town of Big Tree, Calif., on a blazing hot day of a long dry summer, in this well-crafted western by veteran Pronzini (The Last Days of Horse-Shy Halloran). A huge shipment of munitions is a-sittin' in Big Tree just a-waitin' to be stoleand they're a-goin' to do it. But the burglary gets bungled, an explosion sets the town on fire and there is only one way out of the parched valley for the townsfolkby train. That way lies peril, however, for not only is the only locomotive in some disrepair, but the munitions are on board, and the fire is spreading fastas fast as the train is racing.
