Metamorphosis

“Do not be deceived.”

An evil spirit that can change faces has slipped into the household of Kang-goo (Sung Dong-il), a priest's brother, and begun wearing the faces of the people inside it. Jung-soo (Bae Sung-woo) can see it happening to one of his own, and he has to work out who in the family is still who they say they are. Kim Hong-sun gives him no time to be sure, and a brother's life is the price of a wrong guess.
