A man returns from a trip to Peru rich and looking for a wife. While still single, he has a real estate agent show him a house or two. The agent invites him to dinner, during which the agent and his wife start bickering, causing the poor fellow to rethink marriage over. He does still want to share his home with someone, however, so he has the agent's sister-in-law move in. Eventually, they fell in love.
