In the midst of a brutal Balkan conflict, a deaf and mute young girl named Angel is captured and forced into a grim existence within a brothel run by the sadistic Viktor. This brothel serves as a den of torment for kidnapped girls who are drugged and exploited by soldiers. Due to her unique abilities and agility, Angel is tasked with maintaining the captives, injecting them with heroin to keep them subdued. Her small stature allows her to move through the secret crawl spaces in the walls, providing her a measure of autonomy unknown to the other girls. Although subjected to immense cruelty herself, Angel formulates plans of rebellion in her mind as she silently navigates her harrowing environment.

Angel's life takes a turn when she befriends Vanya, one of the captives, forming a bond through their shared suffering. This newfound companionship ignites a spark of defiance within her. As tensions within the brothel escalate and Viktor’s brutal rule becomes increasingly unbearable, Angel’s daring spirit leads her down a treacherous path. With each step taken, she is pushed further towards the brink of a perilous escape, setting off a chain of events that will irrevocably change her fate.
