Unknown slayer/gore movie

Once i saw a movie about a girl trying to scape from kidnappers who had yellow smiling masks. The name was some sort of "smile", "smiling" or something like that, so I am struggling to find it because of the new movies with that name. It was gore, the girl gets beaten then leaven, she tries to escape, but those men get her, beat her and leave her again a couple of times. Any remember? It's before 2015, low budget
