Charlie Scott tells the gang that he has a great idea for the summer--building a clubhouse in the lot behind his house! All it takes is some scrap lumber, used nails and old tools.

At first it looks like Charlie has everything that anybody needs; then his Aunt Essie comes for a long visit. She has plans of her own, and a clubhouse for Charlie and his friends doesn't fit in with any of them.

With so much to think about and so much to do, Charlie Scott can see that it's going to be some summer at his house!
