There was this movie that I THINK was on lifetime, and it was about a girl that was locked inside of a white warehouse with a bunch of rooms that were like solitary confinement rooms or something. I think there were other people in the rooms too. She escapes and she gets to the cops and they try to convince her that it never happened or that she is crazy.
I’m not sure it was on lifetime, hell it might have been an episode on criminal minds or something. It was before 2018, somewhere in the early 2000’s. (There is a chance I imagined this as I was very young when I watched it)
