Mana is a schoolgirl who grew up in a wealthy household, living a life without worries or hardship. One day, on her way to meet her boyfriend, she is suddenly attacked and kidnapped by a group of homeless men. They take her to an abandoned house, a dilapidated old home filled with a dark and eerie atmosphere. There, she is subjected to the cruel and depraved desires of these men. No matter how much she cries, screams, or resists, she is overpowered and forcibly pinned down, enduring repeated rape every day. As time passes, Mana's mind gradually breaks down, reaching the brink of complete psychological collapse. Eventually, she becomes pregnant with a child whose father is unknown. A nightmare-like tragedy descends upon Mana.
