A sunny day at the park becomes a duel to the death when two lemonade sellers turn to guerrilla warfare in a battle for customers.

The gang offers to help their pal Waldo attract customers to his lemonade stand. Redecorating their clubhouse as a lavish nightclub, the kids stage an elaborate floor show, with Darla Hood as the star vocalist.

Seth and Dave are two friends. They're normal people. They laugh. They cry. They bleed. When it rains, they open umbrellas. When it's cold, they put on coats. And when it's hot, they seek refreshment. But that's easier said than done.
