Serena, the true heiress, returns to the estate with the "black box of death" from her mother's plane crash. She is cruelly humiliated by her scumbag father Victor, the fake heiress Bella, and her own brother Julian, and is thrown into a leaky, abandoned boiler room. They think forcing her to sign away her inheritance will ensure their comfortable lives—but they have no idea that this meek, country girl is actually the secret mastermind behind Apex Global, the powerhouse that controls Wall Street, and a world-class genius hacker. The queen, lurking in the shadows, declares that the countdown for the murderers has begun. Serena restores the black box using her bare hands to splice high-voltage electricity, uncovering ironclad proof that her father murdered her mother. She methodically cuts off the family's funding chain and traps her father into signing a "ten-billion-death wager" contract. At the heir's banquet, an armored convoy crashes through the gates, and Serena, dressed in a rare haute couture gown, makes her domineering debut. She publicly plays a video of her father's scandalous affair with the fake heiress and releases the murder recording, sending all her former tormentors to hell. In the end, the estate is leveled by bulldozers. The queen, standing atop the ruins, boards an armed helicopter and flies away resolutely toward the sunrise.
