Lin Wei silently supports her husband Chen Mozhe’s career using her family’s resources, only to discover through a crack in the office door that he is having an affair with Su Na, who disguises herself as a distant elderly aunt in her sixties. Heartbroken by Chen Mozhe’s betrayal, Lin Wei resolves to take revenge. She first replaces the one-way office glass with two-way glass, then prepares handcuffs and aphrodisiacs, luring the pair to a meeting. Inviting shareholders and reporters, she watches as Chen Mozhe and Su Na, under the influence of the drugs and locked together by handcuffs, expose their secret in a panicked frenzy. Su Na’s fake identity as the elderly aunt is repeatedly questioned, but she manages to bluff her way through. Lin Wei tightens the noose, revealing evidence such as sex toys and ambiguous notes, arousing growing suspicion among the attendees. To prove his innocence, Chen Mozhe falsely claims to have a venereal disease, but Lin Wei forcibly takes him to the hospital for examination. As the plot unfolds, Chen Mozhe’s parents intervene, accidentally exposing Su Na as the mistress. Su Na claims to be pregnant, but Lin Wei shatters the lie. Ultimately, under Lin Wei’s scheme, Chen Mozhe is castrated, Su Na’s child (fathered by Chen Mozhe) is aborted, and Lin Wei exposes Chen Mozhe’s embezzlement of public funds and gambling debts. He is stripped of his position and held legally accountable, while debt collectors take away his parents. All traitors meet a miserable end, and Lin Wei successfully reclaims everything that once belonged to her.
