Miley Chase, a 6th grade science ace, wants to discover something scientifically important, something that changes everyone’s lives.
While calculating the exact date the asteroid hit the earth and destroyed the dinosaurs, 10 year-old science wiz Miley Chase accidentally discovers the secret to time travel. She’s putting the finishing touches on her time machine when her nemesis Tyler, the snotty, spoiled next door neighbor, arrives to gloat over his win at the science fair. Despite Miley’s warnings, Tyler gets a little too curious about the machine—and accidentally sends them both to prehistoric times.
They’ve arrived, according to Miley’s calculations, on the same day that the asteroid is about to hit earth. Their biggest problem: the time machine is badly damaged from the crash landing. It is up to Miley and Tyler to work together to avoid being dinosaur dinner and fix the time machine before the asteroid hits.
Using their resourcefulness to build new parts for their ship, the two learn they can accomplish anything if they really try, and that an open and inquisitive mind can turn old enemies—and even long-extinct carnivores—into new friends.
