One hot summer night, two young boys wake from their sleep to the sound of hoots and howls - what's going on? Looking out their window, they discover that "the joint is jumping"! It may be time to sleep everywhere else, but on this Martha's Vineyard farm all the animals and vegetation come out for a nighttime celebration. The boys are invited to join in, as the midnight choir is about to begin. The tulip conductor tries to get down to work, but the rest of the crowd is going berserk! Cantaloupes are laughing, and onions are doing a jig, while an old apple tree plays a driftwood guitar and the hogs chase the pigs. Eventually the morning arrives, though, and the fun is over for the night. But not for long. . .
