According to legend, an ominous entity known as the "Queen of Spades" can be summoned by performing an ancient ritual. Those brave enough, draw a door and a staircase on a mirror, in darkness, say her name three times, and what happens next must be experienced to be believed. Four teenagers decide to summon the Queen as a joke, but they could never imagine the horrors this innocent prank would condemn them and their loved ones to. The evil entity won't stop until she gets their souls.
