Brilliant but befuddled Professor Philip Brainard (Williams) is on the brink of inventing a revolutionary energy source and missing his wedding to fiancée Dr. Sara Jean Reynolds--president of financially challenged Medfield College--for the third time! When Phillip experiments with his own big bang theory, a miraculous elastic goo--Flubber--emerges, leaving him ecstatic but unmarried! Phillip and his flying cyber sidekick Weebo soon discover that Flubber, applied to anything, enables it to bounce super high and fast. However, many questions remain. Is Flubber goo enough to win Sara back, save Midfield from its financial problems and slip through the hands of the evil financier who is bankrolling the college?
