In Love and War(1958)

Three Marines take shore leave in San Francisco during World War II. Frankie O'Neill visits his lower-class dysfunctional family; Nico Kantaylis visits his pregnant fiancée; and the upper-class Alan Newcombe visits his high-living playgirl girlfriend. Each must decide whether to make the best of his situation or break out of it. O'Neill drowns his troubles in alcohol, losing the respect of a potential lover; Kantaylis marries his fiancée, but realizes he may not survive the war to see his child; while Newcombe sheds his decadent girlfriend for a pure-hearted Hawaiian nurse. Later, in battle, a heroic act costs one of the Marines his life.
