Three Godfathers (1936)

Four outlaws come to New Jerusalem, a town full of courteous and religious people, to rob the bank. After shooting the president of the bank, only three make it out of town followed by the posse. By the time they get to the second desert water hole, they find it dry and also find a wagon with a dying mother and baby. When the horses are dead the next morning, the three outlaws have no choice but to try to walk back to New Jerusalem and only two want to take the baby.
