Peering at a small band of Indians who depart with their wounded and dead companions Clay moves cautiously to the crest of a hill. His intervention has sent the Indians racing for safety but the danger is not over. He sees an overturned wagon resting on its stays half in and half out of a streambed. Beneath it lay two terrified youths their eyes wide their mouths unwilling or unable to speak. One is Roberta a teenage girl and one Bobby her little brother. Little does Clay know that the three of them will set out on a fighting flight pursued by outlaws who would see them dead.
