Selva walks down a hallway in a permanent shift of horror and disbelief that makes her both scream and laugh. She finally ends up at a peaceful wall painting of a forest lit in warm daylight. She is struck by it for a second, then bends back her body to scream into the void. Played by a truly unchained Sofia Boutella who finally gets to showcase her entire range of artistic expression, Selva is a dance choreographer, who agreed to train a small circle of students assembled in a remote school building for some sort of winter dance camp. It seems barely hours prior that she was less existentially disturbed and in possession of severely more chill. The same counts for the rest of the now completely deranged group of dancers.
