Dae-su finds a hypnotist. He asks to have his memory of Mi-do’s identity erased. The hypnotist warns him: “You will still know something is wrong. You will still feel the guilt. You’ll just never know why.”
He begins hunting. With the help of an old internet café worker (who owes him a gambling debt), he traces the prison: a private “rehabilitation center” run by a man named Mr. Han. But Han is just muscle.

Then—nothing.
