A child's resilience and the kindness of strangers. Thuy is 10, an orphan, working in her uncle's factory outside Saigon. He berates her constantly, so she runs away to Saigon. Over five days, we watch her survive on the streets selling flowers, while her uncle looks for her. She encounters Hai, a reserved zoo-keeper whose fiancée has jilted him. She also sells a flower to Lan, a flight attendant in the city for a layover, unlucky in love, who buys dinner for Thuy and offers her a place to stay that night. Thuy, who thinks of Lan as a sparrow and Hai as an owl, determines to bring them together. If she succeeds, then what; and what about her uncle?
