When five teenage girls are abducted, Chicago PD Detective Billy Harney leads the investigation to find them.

Harney and his partner, Carla, follow a lead to a remote house, only to find themselves caught in a deadly trap. A huge explosion rips through the building, killing Carla and allowing the kidnapper to escape.

With the loss of his partner fuelling him, Harney strengthens his resolve to find her killer - and to make sure the body count ends there.
