To his wife Diane, his family and friends, Alan Masters is a good guy; a successful attorney on the side of law and order. But to the hoodlums who run Chicago's rackets, Masters is a useful ally; a ruthless, powerful man who has the city's cops and judges dancing to the mob's tune of violence and corruption. Masters believes he is untouchable. But when the decomposed corpse of his young wife turns up in the boot of a car, he's a prime suspect and must face the one cop in town who can't be bought - Detective Sergeant Jack Reed. Though in danger of paying with his own life, Reed vows to bring the killer to justice; and end, once and for all, Masters' bloody reign of terror.
