I saw this trailer for a movie way back. If I would guess when I’d probably say around 2010. In the trailer. There’s this girl who is riding in a car with her friends but she falls off of it and it doesn’t seem like anyone notices. She later wakes up in some old guys couch with a blanket on her and the old man comes over with a cup of tea or something for her. She thanks him and as she sits up she notices that her leg is chained to the house. She starts running out of the house but the chain stops her just beyond the front door. Then I guess the movies plot is her trying to escape from the man. Also the movie is English and it is not black-and-white. Thanks in advance!
