Backsliding (1992)

While in prison, Jack had two momentous experiences: he got religion, and met the woman who would become his wife. He and Alison are devoted to the idea of staying in God's good graces, so they have moved to a remote power station in central Australia, far from anything. Into this possibly idyllic arrangement comes a rootless young man who the power company has hired on to be the station's handyman. Tensions escalate between the men as their conflicting values rub up against one another.
