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.

The Avengers and their allies must be willing to sacrifice all in an attempt to defeat the powerful Thanos before his blitz of devastation and ruin puts an end to the universe.
