Three years ago, a horrific tragedy tore through the elite Takahashi estate, leaving an unsolved mystery. The world moved on. Until tonight. When the head of the Takahashi family is brutally murdered, a chilling phone call forces a group of select individuals—leading police inspectors, the family's estranged daughter Naomi fresh from America, and high-profile suspects—into an isolated mountain mansion. Waiting for them is a grand celebration. A feast of the macabre, where the doors are sealed tight and survival is the only objective. Paranoia spreads like wildfire as the guests turn on each other, hunting for the monster among them. But in a house full of sinners, the most dangerous weapon isn't a knife or a gun. It’s the quiet, innocent smile of the man watching them tear themselves apart from within. Welcome to the banquet. The table is set, and tonight... death is the guest of honor.
