The Rest of Heaven Was Blue (2013)

A young soldier in the Vietnam War struggles with a personal descent into purgatory. Ravaged by a firestorm of bullets, grenades, and napalm, he finds himself in a moral abyss, tormented by grotesque visions of dead soldiers and hounded by an illusory phantom figure. Relentlessly moving through the warzone, the violence escalates to the most vile and base sort as his misery traps him in a sea of indecision while caught in the wake of atrocities under the driving force of his vicious platoon sergeant. If Heaven hides nothing from us, then neither does Hell.
