A mysterious nightmare traps four unlikely allies inside a sprawling mansion where the rules of reality no longer apply. Stripped of their supernatural abilities, Reiri, Riza, Hiro, and Hime must rely on their wits and teamwork to survive encounters with twisted creatures and unforgiving obstacles. The disappearance of their companion Flandre becomes their first clue that something is fundamentally wrong with their surroundings. When they manage to break through an illusion, reality fractures further, revealing layers of deception that threaten to consume them entirely. What follows is a desperate race through corridors that shift and reform, forcing the group to confront both external horrors and the psychological weight of being powerless. Every corner presents a new threat, and every decision matters when escape depends on outsmarting an environment designed to break them. The special balances genuine danger with absurdist comedy, creating moments where humor and dread collide unexpectedly. For viewers who enjoy horror that doesn't take itself too seriously, this delivers both scares and laughs while keeping tension simmering beneath the surface.
