 Garcet, a young French officer just out of military school, joins the French Batallion of the United Nations Forces fighting in Korea. He is disappointed at first as he is assigned as liasion officer behind the lines. Later he is given a combat command. There, he has to win the loyality and frienship of his fellow officers and the men. Although all are volunteers, many are puzzled as to just what it is they are fighting for in this remote and desolate corner of the world: The cast of "Heartbreak Ridge" is composed of Officers and Enlisted men who fought with the French Batallion under the flag of the United Nations in Korea. Made under the sponsorship of the French Ministry of National Defense with the co-operation of the Officers, non-commissioned Officers and Enlisted men in the volunteer French Batallion.
