Ellie, Lex, and Will are back for a summer adventure and challenge. Their favorite park is run down and rusty. An accident on the last day of school proves to be the last straw. They need a new park. When City Hall says there isn’t enough money to replace the park, the three set out to raise the money themselves. Their fundraising begins with a wet dog wash, a lemonade stand, and yard work for their neighbors. Will their hard work inspire their community to come together and build a new park?
