Charlie and MacLeod come to the aid of Sara Lightfoot, an Indian woman on the run with a baby. She tells them Avery Hoskins is trying to steal her baby. Hoskins and his brothers come after them, and they are forced to flee overland. After a rugged flight through a mountain canyon, MacLeod learns that the baby is in fact Hoskins’ son, taken by Sara in retribution for her own child, killed by runoff from Hoskins’ mines.
