Bo Ba Bu plot
A woman stumbles parched through the desert, voiceless, and apparently without memory. A sheep herder finds her, ties her with a rope behind his cart and drags her to his house. He lives there with another shepherd, probably his brother. The woman becomes their property. She is assigned clothes and a cooking pot. But the balance has been disturbed. When the older and strongest of the two men claims the woman for herself, she unwittingly drives a wedge between them. She becomes a burden and they put her back in the desert. But the shepherds are the woman's only chance of survival, so she comes back. They won't lose her. And actually they don't want to. Either way, the damage has already been done, with or without the woman. Living together as before has become impossible forever.
