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."
