In an isolated forest in the Vietnamese countryside lives a man with his unwed daughter and mentally different son. Obsessed with keeping his bloodline, he tries to get his son to be able to plant his seed in a wife provided for him. Such is not easy to purchase, but in his own household he finds the solution.

Excellent cinematography.
