Pediatric nurse Xia Lin was born with the ability to understand baby language, but hid her talent for years due to childhood trauma. On her first day on the job, she heard the inner voice of the critically ill baby Noah—the child wasn't beyond saving, he just hated the baby bottle. She bravely spoke up, saving Noah and also uncovering a conspiracy targeting children. Facing doubt and danger, she chose not to turn a blind eye and deaf ear anymore. In the end, she not only protected Noah, but also met someone worth entrusting her life to, building a warm home. It turns out that bravely listening and bravely speaking up are the best redemption.
