Detectives Tim Entenok and Tom Armelli are called to the scene of a grizzly family shooting. Two adults and three young children have been killed. Detectives work their way through spent bullets, shell casings, and other evidence at the scene, including two firearms, to piece together what happened and discover what led to this violent family massacre. Was it the result of a home invasion or a domestic dispute? And where is the missing upstairs neighbor? Detectives send all available officers into the dark night to find a violent, brutal killer before he can cause more devastation.
