This is a trailer for the upcoming horror film You Shall Not Sleep (No Dormiras).

"In an abandoned psychiatric hospital, an avant-garde theater group experimented with insomnia for the preparation of the montage of a work created twenty years ago by a group of patients. With the passage of days without sleep, they reach new thresholds of perception, that face them to energise and histories hidden of the place… When Bianca, a young promise of the theater, joins the cast, competing for the lead role, must survive not only the intensity of work and her companions, but an unknown force that pushes her, like the others, to the tragic Denouement of the original staging."
