Plot
Homer Smith, just out of the US Army, buys a station wagon in Seattle, equips it for sleeping in and sets out to see the West. Having learned many skills in the army, he picks up jobs as an itinerant handyman/jack-of-all-trades.
One morning, Smith comes to a derelict-looking farm in a valley west of the Rocky Mountains. He sees several women working on a fence, very ineptly. The women, who speak German but very little English, appear to be Catholic nuns. He offers to do a small repair job and stays overnight, assuming that he will be paid in the morning. The next day, Smith tries to persuade the Mother superior to pay him, but it is clear that Old Mother—as he now calls her—is convinced he has been sent by God to build a church.
