Hi I’m trying to think of a film only few years ago , it’s about a big house where girls are kept and used by the owner I think as prostitutes and drugged but there’s a younger girl that washes them and takes care of the girls and cleans up their wounds . She ends up inside the wall and vents trying to escape a group of soldier type men that are horrible to the girls and she kills one so they are trying to kill her .

Anyone know the film please ?
