Late one evening, Bill Greer as well as his son Jackson patrol their ranch when Jackson inadvertently eliminates an immigrant Mexican young boy. When Bill tries to take the blame for his kid, Jackson takes off southern on horseback, ending up being a gringo "illegal alien" in Mexico. Chased After by Texas Rangers as well as Mexican federales, Jackson journeys throughout Mexico to look for mercy from the dead boy's father just to love the land he was educated to dislike.
