Lim Soo-ho was a North Korean spy who had just managed to narrowly escape a horrible car crash. He rushed out of the car, disoriented and possibly a concussion, and ran in the opposite direction from the police that were chasing him. Lee Gang-mu was on his tail, following Lee Soo-ho through the rugged terrain up the hill. Gang-mu shot fires at him blindly, hoping one hit would land and help them catch Soo-ho.

Soo-ho rushed up the slope but just when he thought he was in the clear a bullet catches him behind his shoulder, sending him tumbling down the steep slope and hit the fence at the foothill.

Gang-mu runs after him, forcing Soo-ho to push past the pain and climb over the fence. He's arrived at a large women's dormitory--now he has to find a way out or a place to hide. He looks around but sees no clear escape, until he sees a window open.

With great effort, he climbs the building's wall and grunts through the window and topples inside and goes unconscious.

You just came back from the library with a load of books in your arms and made your way to your dorm humming a familiar song.

Unsuspectingly, you open the door but find a mysterious man limp on the floor near the window. You instantly drop the books on the floor and panic. You rush over and kneel down on the floor and instantly recognize this man as the one that had joined you and your friends on a blind date.

Unbeknownst to you, the school dean had just announced everyone to lock their doors as they had suspected an intruder amongst their walls.
