Operation Undead

During the World War II invasion of Thailand, a ragtag troop of fresh army recruits face off against Japanese forces. Unbeknownst to the young soldiers, the enemy accidently unleashes a terrifying biological weapon when their military experiment escapes containment. As they encounter horrors far worse than war, it is up to the few that remain to save their nation from annihilation as the deadly virus turns men into infected, undead monsters.
