Masked Socialite: My Cellmate Is a Top Tycoon Heir

Amelia arrives at the Walker estate as the family's long-lost daughter, greeted by relatives who smile at her and gossip behind her back and by a fiancé chosen for the match. She learned the details of the Walker family, the estate layout, the old arguments and the private nicknames, from Isabella while the two of them were locked up together. Isabella is the real Walker heir, taken from the hospital as a baby and raised elsewhere while her stepmother installed a substitute daughter and stole her mother's shares of Walker Group. Amelia's own reason for the disguise is separate: she was framed for a crime she did not commit and wants the money and the standing to take down the man responsible. At the engagement gala, with the ring almost on her finger, Isabella walks in as an invited guest. She has also just gotten out of prison and recognizes Amelia immediately, since she is the one who gave her the information in the first place. Rather than expose her, Isabella offers a deal. Amelia keeps the false identity and pursues her revenge, and in exchange she uses her position inside the family to help Isabella get back her mother's inheritance and the Walker Group shares the stepmother took. They split the work. Amelia collects evidence from inside the house, sitting through family dinners and board meetings and pretending not to notice the stepmother's digs. Isabella runs things from outside, tracing bank transfers and old hospital records. Between them they embarrass the stepmother and the biological sister more than once when the pair try to unmask Amelia as a fraud, and they take apart the reputation of the man who framed Amelia in the first place, piece by piece, through leaked documents and a staged confrontation in front of his own business partners. As the fight over the inheritance comes to a head, the stepmother pays someone to arrange an accident meant to kill Amelia. Isabella pushes her out of the way and is hurt instead. In the hospital, with Isabella still bandaged, they stop pretending to each other about what they feel. At a Walker Group shareholder meeting, Isabella produces a DNA report and the paperwork on the transferred shares, proving who she is. Amelia follows with documents and recordings proving the stepmother murdered the first Mrs. Walker years earlier and embezzled company funds afterward. Isabella is confirmed as the heir and takes back the shares and the inheritance. Amelia gives up the Walker name in front of everyone. Isabella hands her a sum of money before she goes, enough to start over somewhere else.
