While exploring a local cave system, best friends Sam and Alissa become separated from their class and stumble into an undiscovered cavern. Here they find ancient cave paintings, alongside two small handprints—perhaps those of the original artists. Sam and Alissa press their own hands against these prints and are zapped back in time! The two modern day children are now lost in a world of pet mammoths, fast-paced hunts, and daring escapes from the claws of saber toothed tigers. How will Sam and Alissa find their way home?
