Informant: Letter from San Francisco

Shan Lan grew up with her grandmother and was estranged from her parents. One day, she received the news that her grandmother's sister, who lived in San Francisco, had passed away. Since her great-aunt Shan Yu had no heirs and no willed heir, the lawyer contacted Shan Lan's grandmother after many setbacks and hoped that she would go to the United States to handle Shan Yu's funeral and inheritance. Because her grandmother is old, Shan Lan decides to take care of her trip to the United States, but unexpectedly she takes the path she has always been afraid of.
