Asian movie(I think. I’m not sure if it is a movie) about a woman who is walking home from work or something and throws up somewhere later on and then she gets kidnapped buy some guy. She was chained to the bed and had to pee in a metal pan. She eventually gained his trust so he unchained her. At some point, she attacked the guy with a screwdriver and stabbed him in the leg, eventually escaping. The guy chased after her, bur I don’t remember the reat. I watched this on youtube A pretty long while back, but I can’t remember the name of it.
