Life is hard for anyone in the wake of an accidental ice age and subsequent military take-over. Wendigos, mutated cannibals affected by a government-released virus, exist at the edge of society, avoiding the government Enforcers who patrol the city streets and preying upon any human unlucky enough to be turned out on their own. Jason, a Wendigo, lives alone with his dogs in his claimed territory. Shunned by his family, except for his missing brother, Jason's one goal beyond survival is to discover his brother's fate. To this end, he strikes a deal with Amica, a human investigator who has her own quest: to take revenge on the Wendigos who killed her daughter. Cooperating for mutual benefit, the two travel across the frigid landscape, witnessing the atrocities of a government caught up in its own greed for control and discovering that humanity is not necessarily a human trait.
