A ordinary waitress Lila is blackmailed by the Voss family’s housekeeper Elena and her master Victor—due to her 92% DNA match with the missing heiress Clara, she is forced to pose as Clara to help them seize the family’s assets.
During her reluctant impersonation, Lila is repeatedly tested by Clara’s fiancé Miles, catches a glimpse of a figure identical to herself (Clara), and gradually uncovers the conspiracy: Clara was imprisoned by Elena and Victor for discovering their embezzlement and illegal transactions.
Miles pretends to help Lila escape, gaining her trust to find Clara’s hidden evidence, but betrays her later—he has always been in cahoots with Elena and Victor.
When Lila is imprisoned, the injured Clara suddenly appears, ready to expose their crimes with evidence. In the chaos, Miles betrays Elena again, while Victor pulls a gun, revealing more secrets of the Voss family and leaving a cliffhanger for the sequel
