Shane Cleary, a PI in a city where the cops want him dead, is tough, honest and broke. When he's asked to look into a case of blackmail, the money is too good for him to refuse, even though the client is a snake and his wife is the woman who stomped on Shane's heart years before. When a fellow vet and Boston cop with a secret asks Shane to find a missing person, the paying gig and the favor for a friend lead Shane to an arsonist, mobsters, a shady sports agent, and Boston's deadliest hitman, the Barbarian. With both criminals and cops out to get him, the pressure is on for Shane to put all the pieces together before time runs out.
