Five-year-old Be Nang (Kim Thu), a smart and adorable girl, lives with her mother Trang—affectionately called Mama Rain (Thu Trang), who is mentally challenged and simple-minded. Every day, the two depend on each other in an abandoned house, making a living by selling lottery tickets and collecting scrap. Be Nang and Mama Rain are always cared for by Mr. Ba (Hoai Linh), who provides them with bowls of noodles on days when they don't have enough money to survive. Will the mother and daughter’s life continue to be peaceful with the love they have for each other?

Based on a famous MMORPG in Vietnam.
