When Emily, a young and unassuming secretary, is drawn into the twisted schemes of her billionaire boss Dominic, her quiet life is turned upside down. Dominic arrives at Emily's doorstep with a gunshot wound, claiming his wife Vivian tried to kill him. Desperate, he begs Emily to go undercover as a maid in his lavish penthouse to spy on Vivian, whom he suspects is cheating and plotting against him. Torn between her loyalty to Dominic and her growing unease about the situation, Emily reluctantly agrees, only to find herself plunged into a tangled web of lies, betrayal, and deadly secrets. As she begins uncovering the truth, Emily discovers Dominic's wound was self-inflicted as part of a twisted plot to frame Vivian and gain full control of the family's vast fortune. But Vivian is no helpless victim - she's a cunning and ruthless schemer in her own right, determined to protect her own interests and expose Dominic's deception. The two engage in a high-stakes game of cat and mouse, each trying to outmaneuver the other while keeping their own illicit activities hidden. Caught in the middle, Emily must decide whether to expose Dominic's sinister plan or continue playing along, all while navigating her own conflicted feelings for her deeply flawed and manipulative boss. The situation spirals out of control, leading to a violent and deadly confrontation that leaves everyone's true motives and loyalties in question. Events take another tragic turn when Lady Martha is found dead in her bedroom in their family home. A detective is brought in to solve the case, and Emily is framed as the killer.
