A sniper in the elite FBI Hostage Rescue Team, Grant was forced to shoot the son of a prominent racketeer in the line of duty. In retribution a contract was placed on Grant's family, resulting in their murders. Frustrated after a year passed without the killer being brought to justice, Grant attempted to take the law in his own hands, ending his career in the FBI. Now he is a forty-year old security guard, embittered by the lust for vengeance, and laden with grief over the loss of his family. While at the mall he interrupts an exchange and gains possession of a briefcase. The case belongs to the assassin who killed his family, Jimmy "Boom" Tedesco, and he wants it back. As an incentive he offers Grant the cure for the poison coating its handle. When the two men meet, Grant wants nothing more than revenge, to spill the hit-man's blood. But his vengeance will have to wait. Though reluctant, he is convinced to help the assassin fulfill a mission of mercy. A mission to rescue a kidnapped family and to help the killer salve his own remorse laden conscience. But, Grant makes one thing clear: "When this is over, no power on heaven or earth will keep me from sending you to hell." An action packed adventure with two reluctant participants; one seeks redemption, the other retribution. Who will survive?
