Unfortunately, someone else also wants the property, so he can strip-mine it and turn the land into a waste-land. Ben's wife and Little Joe's mother is killed when the store in which Ben is working in at the time is blown up by the miner, the one who takes her death the worse is Little Joe. Shortly after this (and because of it) Ben is awarded the property. All seems to be said and done, but as Ben and the boys are building the house, in the middle of the night the miner sneaks onto the property and pours kerosene all over the house and ignites it. Little Joe takes Ben's gun and goes hunting down the miner, not realizing the new trouble he could be causing because of it. Meanwhile, two other characters come into play. The first is Carlos (Fernando Carrillo), a Mexican Soldier who returns to the town after being in the
