Moscow. High-rise. Here, on the 12th floor, is the office of the call center “Online store for adults”. One morning, arriving at work as usual, twelve people who find themselves in the office suddenly find out that there is a bomb in the room. Voices of unknown persons, who introduced themselves as Dad and Mom, threaten to blow it up at any moment if the hostages do not follow their instructions. While the countdown is going on, they will have to experience the absolute power of invisible sadists and learn about each other’s life that they did not even know about.
