Chon, a med student, starts seeing a psychotherapist after he dreams about a woman who he had only met once in a restaurant.In his dreams, a mysterious man murders her, slices her body into pieces, and flushes them down a toilet one by one.
The murderous dreams haunt him into his waking memory, and eventually he feels as if his own body is being dissected and carved up by the surgical knife. Slowly, the terrifying images take control of him. He comes to believe that the dead woman is sending him messages through these nightmares.
But these are not messages for him, they are meant for her murderer. They speak of revenge, and say: "I am still here."
