Every week, a handful of people will be dragged into a nightmare that they might not wake up from again. Without any rhyme or reason, with no pattern to be seen, the public is at the mercy of the mysterious phenomenon that takes people's lives like a forced game of Russian Roulette.
In the midst of all this, two young men are dragged in as well. An unlikely pair with more similarities than they expect at first - a cold-blooded murderer and an exhausted genius, two people that bloom in the cruelty of the nightmares rather than within the safe environment of society.

In the game of gamblers, who will care that you lost your mind as long as you keep your life?
