An abnormal heat has covered the city, completely changing the pace and rhythm of normal life: only in the dark can you work, move, and survive. And it is in the middle of the night that Samantha Andretti returns from the darkness that once consumed her. Fifteen years, since she was kidnapped on the way to school, she spent in a labyrinth, did not see the sun, flowers, trees, did not look in the mirror. A young woman is placed in a hospital ward. Doctor Green, who is watching over her, hunts not for monsters in the outside world, but for the consciousness of their victims. Perhaps Samantha's memories can lead to the trace of who kept her captive - the man from the labyrinth.
