Into The Mirror 2003

Dreampia Department Store is preparing to re-open after being closed for a year due to a mysterious fire. Inside the store, a series of horrific serial murders are discovered. Late at night, an employee in the planning department Choi Mi-jeong is found in the restroom, having slit her throat with a pizza cutter. Afterwards, Section Chief Kim from the General Affairs department dies alone at night in the elevator with a ballpoint pen thrust into his ear canal. The only commonalities in the cases are their location in front of mirrors, and the severe shock which helped to bring about their deaths.
