Willie Wade, an eight-year-old genius with an I. Q. of 180, would rather program a miniature computer or lay our plans for the construction of the first bionic rabbit than play baseball. With the hope of helping mankind, Willie invents the box. An electrical gadget that can open and close supermarket doors, automatically change traffic signals, and regulate the towns power supply by remote control. The misuses and frequent malfunctions of the box creates some challenging and very funny encounters between Willie and his father, the local sheriff.
