The silence of their shared bedroom, the memories of Mitch's guidance, and his mother's drunken spiral are constant reminders of the cost of his absence. But Mark isn't ready to grieve. He isn't ready to accept that his brother is truly gone. Despite the insistence of the adults in his life that he accept Mitch's death, Mark is undeterred. They don't know what he knows.

Aided by his loyal band of misfit friends, Mark's plan to carry Mitch's ashes to the witch is complicated by the pursuit of the town sheriff and the cousin responsible for his brother's death. With no time to regroup, Mark and his friends must navigate the dangerous path to Spook Hill before the sun sets, so that Mitch can be resurrected in exchange for the life of the one who took it.
