I'm a Cyborg, But That's OK

More about this movie

A young woman who believes she's a cyborg hears voices and harms herself while at work making radios. She's hospitalized in a mental institution where she eats nothing and talks to inanimate objects. She's Young-goon, granddaughter of a woman who thought she was a mouse (and whose dentures Young-goon wears) and a mother who's a butcher without much social grace. Young-goon comes to the attention of Il-sun, a ping-pong playing patient at the institution who makes it his goal to get her to eat. Will he succeed? Which way does sanity lie?
