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 stole-and 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 townsfolk-by 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 fast-as fast as the train is racing.
