Department store sales clerk Byun Ji Sook (Soo Ae) has been trapped in a horrendous cycle of debt thanks to her father and brother. Everything changes when she encounters Seo Eun Ha (also played by Soo Ae), a wealthy heiress who looks just like her. Eun Ha is engaged to Choi Min Woo (Ju Ji Hoon), the heir apparent of a massive conglomerate, but his status as an illegitimate son puts other family members against him. Unbeknownst to Min Woo, Eun Ha is having an affair with his half-sister’s husband Min Seok Hoon (Yeon Jung Hoon), who wants the company to himself. When Eun Ha ends up dead, Seok Hoon blackmails Ji Sook into taking Eun Ha’s place, launching her headfirst into the perils of high society. Will Ji Sook find a place for herself in Eun Ha’s world – and can she help Min Woo avoid a horrible fate of his own?
