There was this movie where a woman got in an car accident or something. Then she woke up at the morgue, with a man well aware that she was alive who were going to prepare her for the grave. To kill her by burying her alive (serial killer). I think she has a boyfriend, and he is looking for her. She gets to know her capturer, who I think made her get in the accident in the first place. He starts to get cold feets, and tells her that she can go if she wants to. But she doesn’t want to. It ends with her being buried and I think her boyfriend found out just a little too late, I think it ended with him standing on her grave maybe digging or something. I’m not too sure.
“After. Life” (2009)?
Correct
