It wasn't an actual series, only an hour long thing. It aired maybe, I dunno, four or five years ago?
I remember some of the kids wore masks.
I know the description is awful, and I apologize. I have a terrible memory as it is. I can hardly remember why I enter a room, let alone remember stuff I watched when I was like, ten or eleven.

Again, I'm sorry, but that's all I've got.
