The spies are on the trail of a villain who is abducting the greatest minds of the world. The spies make the connection that the people being abducted are experts in the same subjects that their tests at school are based on. The spies discover that a diabolical father has found a way to transplant the intelligence of the geniuses into his son's brain. Incidentally the son goes to the spies' school. Can the spies stop the villain before their own intelligence is reduced to that of a rodent? In a b-story, Clover and Sam fight over a part in the school production of "Les Miserables."
