Having lost much of his memory from a traumatic brain injury sustained in Iraq, army veteran Matthew Rose is called back to Montana after his father's death to settle his affairs, and hopefully to settle the past as well. It's not only a blank to him, but a mystery. Why as a teen did he suddenly become sullen and vacant, abandoning the activities and people that had meant most to him? How did he, the son of hippy activists, wind up enlisting in the first place? Then on his first night back, Matthew sees a house go up in flames, and it turns out that a local college student has died inside. And this event sparks a memory of a different fire, an unsolved crime from long ago, a part of Matthew's past that might lead to all the answers he's been searching for.

Late summer, 1921: Disgraced former lightweight champion Pepper Van Dean has spent the past two years on the carnival circuit performing the dangerous “hangman’s drop” and taking on all comers in nightly challenge bouts. But when he and his cardsharp wife, Moira, are marooned in the wilds of Oregon, Pepper accepts an offer to return to the world of wrestling as a trainer for Garfield Taft, a down-and-out African American heavyweight contender in search of a comeback and a shot at the world title. At the training camp in rural Montana, Pepper and Moira soon realize that nothing is what it seems: not Taft, the upcoming match or the training facility itself.
