Quan is a stubborn but mature 11-year-old. One day, coming home from school, he witnesses something that makes him question his family's dynamics.

Toward the end of 1946, residents from all walks of Hanoi struggle to avoid—and eventually accept—the possibility of a full-blown war.

In an old house in Hanoi, Bi, a 6-year-old child lives with his parents, his aunt and their cook. His favorite playgrounds are an ice factory and the wild grass along the river. After being absent for years, his grandfather, seriously ill, reappears and settles at their house. While Bi gets closer to his grandfather, his father tries to avoid any contact with his family. Every night, he gets drunk and goes and see his masseuse, for whom he feels a quiet strong desire. Bi's mother turns a blind eye on it. The aunt, still single, meets a 16-year-old young boy in the bus. Her attraction to him moves her deeply.

Set in a breath-taking primitive landscape in the mountainous provinces of Vietnam, the film tells the story of a Hmong tribe girl named Pao. She was raised by her stepmother, for her real mother left her when she was little. One day, her stepmother dies in an accident, and she begins to track down her birth mother. But her journey turns out to disclose an unsealed sentimental drama of the family in the past.
