Detective Casey Norris has gotten his badge back, after coming out of retirement, and is back in charge of his team of detectives, which features a couple of new members. There is little time for introductions, however, as a new case has hit their desks featuring a monster unlike anything they have ever seen.

Helena has a new serial killer. A killer who has hit a breaking point. A killer who is hunting young families. A sadistic individual who seems to have no limits and who refuses to leave anyone in the city with a feeling of hope or safety.

Norris and his team are in a race against the clock as this new predator allows less and less time between each kill. Norris must work to understand the individual he pursues while fighting through his own personal demons which threaten to derail his case, as well as his life.

Being a part of a family is supposed to create a feeling of comfort and love, but for this killer, it only creates a new target.
