Inspired by the rumored house from the urban legends, the goal of the TV show is to find the “true exit” and escape the house in seven days. To film this, eight celebrity guests were gathered in this strange mansion on a deserted island. The rumor was that you could only visit the mansion with 101 doors when you were at death’s doorstep. When I was seven years old, I met “that child” at that huge house. After I made a deal with the kid in my thoughtless sympathy, I was surrounded by death and black-eyed goblins. What was that child’s identity? I finally made a resolution when the one I loved, Yeonseon, died—I needed to meet that kid, and… But perhaps my wishful thinking was wrong. The death of one of the guests, the actress Goyeon Lee, awakened the malice in the mansion and the seeds of doubt sprouted amidst the people seized in fear and horror… “I came to pick you up. I made you wait, didn’t I? Open the door for me.” A well-made holding pen. There was no escape from this cage. “I told you that you wouldn’t be able to forget me.”
