Ex-FBI special agent Ben Hawkins relentlessly tracks two killers wreaking havoc across the country but has to face off against the darkness roiling inside him. His compulsions drive him to the brink of losing his job as task force head before he barely has the chance to get going.

One of the killers he pursues, Sammy Gill, is on a hunt of his own to avenge the recent murder of his family. The pressing challenge to that mission is the small matter that Gill is in task force custody, legs chained to the floor of a cell. When he finally does break loose, he starts his spree of revenge with the crew of mobster Jimmy Morretti. He moves on to Morretti himself before reaching the frightening end of his search, a confrontation with the killer of his family.

Hawkins charges at breakneck speed toward that same end, along the way finding a surprising connection between the Morretti mob, the two killers he chases, and a shadowy terror organization with tentacles reaching into the far corners of the land. This is a gritty tale of hard-driving hunter-killers heading on a collision course with disaster.
