Up, up and away! She's a girl named Moe who dreams of flying like the sky diver on the Fourth of July. But Madeline "Moe" McDonohugh wants a plane of her own. Her best friend Otto Price agrees. by the next Independence Day, they'll be in the air as the crowds cheer. All they need is money to build the plane.

But their "Elixir of Youth" medicine show is a total disaster, they end up owing money after helping a traveling photographer drum up business -- and destroying Mrs. Dillard's parlor. Then Moe's mom blows a gasket when she finds them hauling lemonade -- made with very expensive sugar -- to thirsty workers digging a new sewer line. Their punishment is doing inventory at Father's store. That's when Moe finds the tarantula in the bananas...and figures out the perfect way to fly!
