Nadia Stafford is an ex-cop - fired after she shot a child killer. She now works for one small mafia family: the way she sees it, no one innocent is getting hurt.

But then a serial killer starts murdering innocent people in the style of a hitman. The police investigation threatens to unmask several professional hitmen, including Nadia. So she bands together with five other hitmen, including her mentor, the mysterious Jack. Together they decide to hunt down the killer - but perhaps that's just what he wants. Are they walking into a devious and brilliantly planned trap?
