Trek follows a young Mormon teenager named Tom and his friends on their handcart journey. Along the way they try to smuggle in unsanctioned food, battle sibling rivalry, encounter a "special ops" Young Men's leader, match wits with a twinkie-loving skunk, and ponder doctrinal brain teasers like, "Do general Authorities go to PG-13 movies?" But, when they encounter unexpected trouble, their faith is tested much like their pioneer ancestors.

Schoolboy Josh Townsend has to move again with his father, astrophysics researcher Dr. Nick Townsend, to a New Mexico small town. To escape the copy-boy job dad arranged, Josh volunteers for the tribal buffalo reserve, working with Navajo clan elder John Blackhorse's cynical grandson Thomas and his buddy Moon. Local scamp Kyle's cool cyclist knaves gang seems irresistible, but their hazing-like demands bring Josh to betray his buffalo friends's reluctant confidence. Written by KGF Vissers
