"Genius" accidentally invents "goo" which causes living things to rapidly grow to an enormous size. Seeing an opportunity to get rich, some delinquent teenagers steal the "goo" and, as a result of a sophomoric dare, consume it themselves and become thirty feet tall. They then take over control of the town by kidnapping the sheriff's daughter and dancing suggestively.
