 McEwen has an completely altruistic motive for robbing the bank, and he sets out on a long journey to fulfill his mission. In his trek across the desert McEwen comes upon a Mexican family who are desperately ill. They will die if he refuses to help and proceeds on his original journey. He shows his true nature and interrupts his pilgrimage to care for the family. Pat Garrett, who has sworn to catch the outlaw, overtakes McEwen at the poor hovel. The climax is suspenseful and is a fitting conclusion to this fine Western adventure.
