Genius lawyer Daniel Reid took on the case of his girlfriend Erin Walker's dad, who had been wrongfully imprisoned, but after losing the appeal, his reputation was ruined. Five years later, he won a high-profile lawsuit for a hearing-impaired girl, Lena Hayes, and returned to the top of his field. At the celebration banquet, Erin discovered that Daniel and Lena were communicating intimately in sign language, and she, having already learned sign language herself, saw through their behind-the-scenes engagement promises. She witnessed Daniel going out of his way to protect Lena, while she herself was abandoned in an elevator accident. She also learned that Lena was the very person who had identified her dad as the perpetrator years ago. Faced with Daniel's betrayal and lies, as well as Lena's malicious framing, Erin resolutely left, traveling far away, and secretly reopened the investigation into the old case, vowing to obtain long-overdue justice for her dad.
