MOVIE TITLE SEARCH

Right I watched this film when I was about 12-13 and I am now 18 and it’s on my mind . I don’t remember it that well but I do remember that it was about like this prison place where they kept young girls , I don’t remember for what reason . And basically these girls came together and tried to escape . But the way they did it is they somehow entered a dream / a simulation where they would have to fight in certain situations to retrieve an item they needed for they’re escape from this prison type place. And eventually they did get everything they needed but I remember in the end only one of them managed to escape as it didn’t go to plan . please help!!!! It must have come out sometime between 2000 and 2012
