After wrapping up her overseas business dealings on the snowy plains, Zhao Guilan returns to her son's home carrying a sack of local specialties, hoping to spend a few quiet days being a grandmother. Hiding her identity and wearing nothing but an old floral cotton-padded jacket, she is mistaken for a country relative who has come seeking shelter and is put up in the housekeeper's room downstairs. For the sake of a ten-billion-yuan project, her son, Lin Zhenhua, turns a blind eye to everything and doesn't even offer her an explanation. Only when the business partners arrive does the truth come to light: the chairwoman of the corporation he has been desperately trying to please is sitting right there in the housekeeper's room downstairs.
