Nels Coxman is a hard-working snowplow driver in the glacial town of Kehoe, a popular ski resort in the Rocky Mountains. Recognized as its "Citizen of the Year," he leads a quiet life with his wife Grace and their son Kyle. Nels’ life is upended when Kyle is murdered under mysterious circumstances, leaving the family shattered. Initially labeled as a heroin overdose, the truth behind Kyle’s death soon unravels, revealing his involvement with a local drug cartel. Driven by sorrow and an unquenchable thirst for justice, Nels resolves to uncover the truth and exact vengeance on those responsible for his son's death.

Crafting a path of retribution, Nels utilizes his intimate knowledge of the terrain and the skills from his civilian life to track down the drug dealers and criminals connected to the cartel. His actions attract the attention of the cartel's unhinged and vicious leader, Viking, who mistakenly blames a rival gang for the series of deaths caused by Nels. As the conflict escalates, the small mountain town becomes a battleground for turf wars between the gangs, while Nels becomes an unexpected but formidable force against the underworld, sparking a chain of events that leads to unintended consequences for all parties involved.
