On Dragon Boat Festival night, a security guard's words tear apart the facade of Vivian Lindsey's marriage: her husband did not return to his hometown, but was secretly meeting his mistress on the 9th floor. Vivian does not cry or make a scene, calmly gathering evidence, only to uncover an even more ruthless conspiracy — they plan to drug her to drive her insane and embezzle all of her family's assets! She proceeds step by step, and sets up an elaborate trap together with her lawyer cousin. At the anniversary celebration, the villains accidentally ingest the poisoned drug and go mad in public, the mistress suffers a miscarriage and is imprisoned, and the scumbag husband is sentenced to prison. She reclaims the company, rises from the ashes, and finds new love.
