As a massive weather system barrels toward them, Vance Township Police Chief Pete Adams and his wife, County Coroner Zoe Chambers-Adams, learn how unprepared they really are. A 911 call reports a dead young mother, her critically injured husband, and their missing seven-year-old daughter. Pete and Zoe realize that as the storm moved north, a killer came with it.
The wounded and trapped father is Zoe's friend, and he asks her to stay with him during the rescue efforts. Pete encourages her to oblige, hoping she can uncover clues that might help the investigation. But as attempts to free the victim fail and his condition worsens, Zoe's questions reveal he doesn't know why his family was targeted and child kidnapped.
Pursuing the murderer and the kidnapped child, Pete and his officers battle downed trees, flooding, and a loss of communications. The killer faces the same problems, yet somehow stays one step ahead of law enforcement. But he is becoming desperate, and more people are dying because of it.
As two lives hang in the balance, can Pete win the race against time and weather to stop a savage and cunning predator? And will he and Zoe be able to reunite a family before it's too late?
