Reverend Conte, a prolific expert on the occult and whiskey, accompanies a ragtag group of rejected military men to a remote South Pacific island to investigate the disappearance of Marine units stationed there in 1944, said to have occurred at the hands of the Imperial Japanese Army. After speaking with the island’s inhabitants, they soon discover that the Marines had actually been massacred by a group of werewolves, known to most as WEREWOLVES.
