Charlie Tuttle is Summerton High's resident genius. An under-aged, pint-sized ball of energy he is on the verge of bending time. But he needs a little help from his friends. Zeke has the mechanical skills to build the time machine, and Virgil is just crazy enough to be the first one to try it. Together they are the Minutemen, sworn to help fellow students get out of embarrassing situations before they happen. But Charlie soon discovers their trips back into the past are creating a black hole and they don't have a minute to spare. This junior genius needs to beat the clock, fool the Feds, save the planet, and hopefully not turn red when Jeanette gives him a victory kiss.
