Summary for the movie
During the Korean War, Matt saves the life of his buddy, Vince, who promises that someday he'll repay Matt by cutting him in on a million dollars. Eight years later Matt is in the midst of a rapidly disintegrating marriage to Nina, a man-hungry alcoholic. Vince suddenly reappears for a reunion with Matt, telling him that enemies of a Central American dictator have hijacked $3.5 million, and that he knows how he can get hold of the money and collect a large reward he'll share with Matt if he will help recover the money. Matt is skeptical, but after a particularly violent quarrel in which he leaves his wife, he agrees to go along with Vince, provided there is no gunplay.
