A lavish launch party for a new gaming app “Werewolves Awaken” has all the media bigwigs in attendance. The young lead developer, August, is promoted as the star talent driving the game's launch. The festivities are interrupted by a priest who condemns the party guests as "marked for the beast." Convinced it's a publicity stunt, the party-goers disregard the protest until a dead body is found. August finds himself caught in a real-life simulation of his game, as the killer continues murdering victims in accordance to the game’s rules. Some even believe these brutal killings are at the hands of something inhuman.
