Emily, a secretary, leads a peaceful life until her billionaire boss, Dominic, arrives at her door late at night with a gunshot wound, drawing her into a conspiracy. Dominic claims his wife, Vivian, wants to kill him and asks Emily to pose as a maid to infiltrate the mansion and secretly investigate whether Vivian is having an affair and plotting the murder. But as Emily digs deeper, she uncovers a shocking truth: Dominic staged his own shooting to frame his wife and seize the family's massive fortune. Yet Vivian is no innocent victim—she is just as manipulative and dangerous, setting the stage for a ruthless battle of deception and survival. Caught in the middle, Emily is not only embroiled in lies and betrayal but is also later framed for the murder in the mansion case.
