Feature-length animated movie. Our favourite boy genius Dexter is literally beside himself as he launches a time-warping, gadget-filled mission to save the future! He must journey into the far future to retrieve his all-powerful Neuroatomic Proto-Core, which was stolen by archenemy Mandark to dumb down the entire planet - leaving the vile Mandark in charge! Fortunately, time is one Dexter's side, in the form of three future Dexters: Dexter the work-wimp, Dexter the geezer and Dexter the muscle-bound hero!
