S1, E1: Adopted as a baby from China, Mei has had a contented upbringing in the UK. She has grown up knowing little about her beginnings, but is the love of her parents' life. One day out of the blue, Mei gets a message from a journalist in China, Pan Qianyi, saying that Mei's birth mother wants to meet her. She is desperate for Mei's help. Her son, and the brother Mei has never met, is on death row for a crime he didn't commit. Suddenly questions of abandonment and identity overwhelm Mei. Qianyi asks her to come to Guangzhou immediately. Telling her adoptive parents only that her mother wants to meet her, Mei is relieved when they agree she should go and that she must take this journey alone.
