A prolific expert of the occult and whiskey, The Reverend, accompanies a ragtag group of military rejects to a remote South Pacific Island to investigate the disappearance of Marine units stationed there in 1944, said to be at the hands of the Japanese Imperial Army. Upon speaking with the island’s inhabitants, the group soon discovers the Marines had actually been massacred by a group of Lycanthropes, known to most as Werewolves.
