Ex-assassin narrator Quarry is offered a million dollars to kill a presidential candidate. Cozily retired, and with a pregnant young wife, Quarry refuses, becoming a 'loose end' to dangerous men who kill his wife. He fakes his own death and heads for the Midwest headquarters of the candidate, a repulsive figure who has a conspiracy theory about Jews, bankers, the Mafia and the British Royal Family. After a great deal of bloody action, Quarry becomes the candidate's security boss.
