After discovering an old box full of clues, Zeke and his three new friends-Sam, Matt, and Dallas-form the Messiah Brigade. Their goal of changing the world for Jesus seems like a huge goal, but they are up for the challenge-and they have a strategy. They are focusing on reaching one person at a time in their school. That's no small undertaking, considering Zeke's school is run by a group of bullies. Thankfully, Zeke knows they're not alone-if only they can remember to be strong and courageous like the Bible says.

This isn't the only problem that the Messiah Brigade is facing. There are still many clues in Nolan's box they need to solve if they are truly going to understand their new covenant. What can a piece of leather with strange markings, a military patch from World War II, and a piece of paper with a note about a boy named Pierre tell them about Nolan Langley's mission?

As Zeke strives to unravel the mystery behind each of these clues from the past, he realizes that change can start in small ways and that courage can be found in something as simple as standing up for your friends.
