It's November 21, 1963. On the eve of their deployment to a small but growing conflict in Southeast Asia, three young Marines set out for one final boys' night of debauchery, partying, and maybe a little trouble. But when Corporal Eddie Birdlace meets Rose, an awkward and idealistic waitress he enlists to win a cruel bet with his fellow recruits, she rewrites the rules of the game and teaches him the power of compassion.
