The Renkins' are having a problem with their grape yard. A group of gophers have made their home in the ground under the garden and are stealing the grapes. Upset with the problem, Mr. Renkins calls Calhoun the Gopher-getter, an exterminator, to come and catch the gophers. George does not like the idea of somebody catching the innocent gophers, even if he does plan to release them again. So he decides to build a connecting tunnel between his house and the Renkins' garden so the gophers can escape.
