Suji, who was spending her honeymoon at a mountain lodge with her fiancé Jin-wook, is raped by four intruders one after another. Jin-wook leaves Suji's side, consumed by guilt for failing to protect her, and Suji spends her days wandering and suffering. One day, Suji finds fingerprints on a cigarette pack left behind by one of the four perpetrators and resolves to take revenge on them. Starting with the first man, gym instructor Ji Yoon-do, she orchestrates the mysterious deaths of model agency employee Moon Sang-woo and commercial artist Jin Jae-kwon, Chanel Jang, making it look like suicide, and then travels to Las Vegas, USA, to find the fourth man, Han Sang-il.
