John 'Nashville' Grant is an American military policeman in the R&R town of Vung Tau, tucked safely behind the front lines of the Vietnam War. Nashville knows how everything works: the army, the enemy, bars, secrets, men and women. He's keeping the peace by keeping his head down and making the most of it.
His new partner is a tall man from a small town: Shorty, from Bendigo. Shorty knows nothing about anything, and he wishes people would stop mistaking that for stupidity.
