On a winter night while shoveling snow, Nora Sterling is driven out of the house by her cruel adoptive mother. She finds a missing person notice in the trash, and a crescent birthmark on her left lower back reveals the hidden secret of her abduction eighteen years ago: she is the long-lost heiress of the Sterling Group. After recognizing her biological family, she hides her identity and joins Sterling Group, starting as a quality inspection worker. With excellent skills, she confronts malicious workplace rivals, resolves quality crises, uncovers the old case from eighteen years ago, and faces off head-on against her old enemy Hector Chow. From an adopted daughter who was once bullied by everyone to the leader in charge of Sterling Group, she walks out of a muddy life relying entirely on her own efforts.
