A long-planned conspiracy, a life that is switched. Charlotte Barlow, the daughter of the wealthy Goodman family, is swapped at birth by the maid Danielle Fuller with her own daughter. Overnight, Charlotte Barlow, who should have been the family's pride and joy, is reduced to a servant's daughter and suffers constant abuse. Meanwhile, Stella Goodman, who should have lived in poverty, becomes the pampered heiress. By chance, Charlotte saves her birth mother, Britney Goodman, and is brought into the Goodman family. Fearing the truth would be exposed, Danielle, who works as Britney's maid, schemes to frame Charlotte, causing her to be wrongfully accused. Stella, who accidentally discovers she is the "fake heiress", also fears her true identity would be revealed. The two conspire with Jordan Goodman, Britney's live-in husband, to poison Britney while repeatedly framing Charlotte, causing her birth mother to misunderstand her! Fortunately, Lionel Goodman, the family's adopted son, helps Charlotte uncover the truth. The two fall in love as they get to know each other and provide mutual comfort and support.
Joanie Sadler and Laurent Goff met and grew up together as children in an orphanage. After leaving the orphanage, Laurent set out to build a career and promised to one day give Joanie a home. Joanie was later adopted by Peggy Boswell and Benjamin Francis, a couple who had lost their own daughter. Peggy sees Joanie as a replacement for her lost child, and when Joanie's birth parents later come to claim her, the Francis couple forges false paternity test results to keep Joanie. Years later, the Francises' real daughter Joanna is found, causing the couple to immediately turn against Joanie and send her back to her birth parents. Joanna also resents Joanie for living the life that should have been hers. At this time, Laurent, through a paternity test from years ago, locates Joanie and arrives at the Francis household, bringing a billion-dollar investment project. However, due to a series of misunderstandings, Laurent mistakenly believes Joanna is his childhood friend Joanie.
