[EDIT]
Here's a little background info on the movie's premise: This is the story of a girl named Erika that is being haunted. How and why you'll find out in the movie. What she can see and what she has seen isn't something people should have to see and causes her much trama. She finds it difficult to believe even her own eyes and it could mean someone's death. (I hope that helps you to understand the girl in the corner and perhaps the movie itself better)

Well this is a trailer of a movie that I'll be putting up here within a month or two. It's very brief, but if you pay attention, you'll get the point.
