When George and Dorothy move to Baghdad to work on one of Mr. Griffin's oil deals, Hazel and Harold move in with George's brother Steve, his wife Barbara, and their daughter Suzy.
Steve has plans to take Susie and Harold fishing. One of his real estate clients arrives at the house and tells Steve he has to find an agent to hold an open house at one of his homes. Hazel sits in as a real estate agent.
Hazel and Barbara go to a land auction. Hazel gets caught up in bidding and wins a plot of land for a few hundred. When she tells Steve which lot she purchased, she finds out it is a small strip of land, just about worth nothing.
Barbara's uncle visits. He is a once-famous actor, out of work and out of money. Hazel and Barbara convince Steve to hire him at the real estate office. A few bad deals later turn into successes. Finally, he gets a call from Hollywood for a part in a show.
Hazel is collecting musical instruments to send to George & Dorothy for a missionary school. She also holds a fund-raiser for enough money to buy an organ.
Steve has a difficult house to sell because it is located next to a busy, and noisy, highway. Hazel finds the perfect couple to buy the house - they are hard of hearing.
