Former professional wrestler Sean Armstrong is lured out of retirement to serve as bodyguard for an inventor and protect him from master criminal Tommy Thanatos, who wants to steal a microchip that could affect the course of world peace. Unbeknownst to Sean, a child-hater, he will also be expected to serve as bodyguard (and nanny) to the inventor's children, who attempt to drive him away as they have driven away every other nanny.
