Irene is sold by her stepfather Carl to the Brade Mafia family to pay off his gambling debts. Her mother kneels and begs her to sacrifice herself. Furious, Irene breaks with her family. While working at a bar, she meets the mysterious Vincent and impulsively sleeps with him on her birthday. The next morning, she leaves money behind and slips away, but is knocked out by Carl and handed over to the mafia's second-in-command, Damian. Escaping, she stumbles into the manor and finds a five‑year‑old mute boy, Luca, whom she believes is being held captive. Out of kindness, she tries to help him flee—unaware that Luca is actually Vincent's nephew. Damian captures Irene again, and just as he is about to assault her, Vincent kicks down the door—revealing himself as the mafia boss. Irene’s fate takes a dramatic turn in Vincent’s hands.
