Her stepmother, Evelyn Sinclair, and sister, Peyton Sinclair, steal her medical papers and take credit for saving Carter Vance in Stonehaven. Having lost her memories, Avery returned home to seek her mother's belongings and unexpectedly reunites with Carter. However, Carter has mistaken Peyton for his savior and is engaged to her. By saving Carter's uncle, Vincent Carmichael, with her genuine medical skills, Avery slowly unravels her true identity: she isn't a biological Sinclair, but the daughter of Celine Monroe and the head of the Rockwell family. Ultimately, Avery reclaims her Sinclair Corporation shares, Peyton's fraud is exposed, and Carter realizes his true feelings, bringing the two of them together.
