There is an ancient ritual known to humankind for more than a hundred years...According to the legend, an ominous entity known as The Queen of Spades can be summoned by drawing a door and staircase on a mirror in the darkness, and by saying her name three times. The Queen of Spades gets her energy from reflective objects; she cuts locks of hair from those asleep, and those that see her go mad or die. Four teenagers decide to call The Queen of Spades as a joke. But when one of them dies of a sudden heart attack, the group realizes they are up against something inexplicable and deadly dangerous.

At 30, Oleg and Seryoga still dream of becoming rock stars. They play in a little-known band, live in a communal apartment, and are preparing for an important performance at a local festival. On the eve of the concert, they are unexpectedly approached by Oleg's uncle, a 50-year-old man with mental disabilities, whom the boys cannot leave unattended, not even for a minute.
