One year after losing one of their own in a tragic house fire, the Taylor (Indiana) Fire Department members find themselves under attack. Someone goes on a brutal killingrampage and firefighters are the preferred target.

As the murders become more brazen—even slaughtering multiple victims at once—Police Chief Erica Kaden and Detective Daniel Cribbs pour themselves into the investigation. As the police department gets stretched thin trying to protect the remaining firefighters, some are convinced the killer is one of the firemen. Several eyes focus on Jake Norton, who had quit the TFD on his downward alcohol-infused spiral after losing his brother in that fatal inferno a year ago. Others believe the murderer can’t possibly be human.

Ellie Beck, a current firefighter and former love interest of Jake, is convinced that he is not involved in the carnage. She teams up with Alice Durnell, who was severely injured in one of the attacks, to search for clues within their own department. Their investigation has one thing in common with what the police have discovered—the seemingly unstoppable killer has his eyes set on Ellie.
