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 hits the earth and destroys the dinosaurs, she accidentally discovers the secret to time travel. Miley’s nemesis, Tyler, the snotty, spoiled next door neighbor confronts her as Miley is putting the finishing touches on the time machine and they are accidentally transported to prehistoric times.
They have arrived the same day in Miley’s calculations that an asteroid is about to hit. But as they land, the time machine is damaged. It is up to Miley and Tyler to work together, to avoid being dinosaur dinner, and to fix the time machine before the asteroid hits.
They learn that nothing is impossible if you put your mind to it, and that friendships can be created in the most unlikely of places.
