The Cat

So-yeon (Park Min-yeong), suffers from claustrophobia, the result of a childhood trauma. But she has a nice life as a pet groomer - that is, until the cops give her a cat to look after. Its owner was just murdered in the elevator. That's when the nightmares start. A little girl, haunting her sleep. So-yeon needs answers. But now, her best friend is dead too, and she doesn't know what to believe. It can't be true. Curses aren't real. Are they?
