The Impossibles are playing a concert at a university when they are summoned to the laboratory. The professor is a friend of their boss, Big D. He informs them that the villain Aquator has stolen a formula and shrunk himself to microscopic size. He asks The Impossibles to get the formula back because he knows who they really are. The Impossibles agree to do it and the professor shrinks them to microscopic size. The professor watches through a microscope as The Impossibles defeat Aquator's micro monsters and retrieve the formula. The professor retrieves The Impossibles and changes them back to normal size. He leaves Aquator microscopic so he cannot cause any more trouble.
