Amid a fierce snowstorm sweeping across rural Minnesota, near the icy shores of Hammer Lake, an isolated cabin goes up in flames, leaving a critically injured high school drug dealer and a missing girl in its wake. The disappearance propels Sheriff Red Hammergren into action to find the troubled young girl, Missy Klein, the daughter of Junior Klein--the victim of an unsolved cold case years prior. As Red peels back the layers of Missy's vanishing, she uncovers a chilling nexus of drug trafficking pervading through her community with roots to the local high school. Unknown to Red, her investigations have roused a malevolent presence, a killer lurking within the storm...a killer that would do anything to stop the sheriff's probing. Red soon reveals a terrifying link between Missy's peril and the unresolved cold cases she has tirelessly sought to solve. Engulfed in a battle against both the elements and time, Red must navigate her community's shadowy corners and frozen woods to rescue Missy and halt the advances of a killer--all before the storm engulfs the truth in its icy grasp.
