Taylor will turn thirteen in one week. He is looking for a leaf for a school project when the school bully, Butch, chases after him on his bicycle. Told never to be close to the river alone, Taylor now rides along the perilous trial hoping to elude Butch. Suddenly, the ground beneath him gives away. He and Butch find themselves falling into a void; a tunnel that takes them to a primitive land. Their adventure takes them into dangerous territory. Taylor wonders if they will find their way back home? Was it all preordained? And if so, for what purpose?
