Teenager Gabe Common and his girlfriend, Millie Themmes, have moved back to Chumsville, the place where the magic that changed them started. Although they attempt to move on with their lives, some forces in the world will not let them.

For one, the ambient magic still exists, and this time it has spread across the state of South Dakota. In fear, the president authorizes the military to contain the Changed, those transformed into something other than human.

Additionally, civilian militias are out to kill the Changed. Once again, Gabe has to lead the residents of Chumsville and fight the intolerance around them, even at the cost of his life. It comes down to not only a battle for acceptance, but also one of survival. The only question is whether Gabe and his friends can survive the upcoming conflict.
