Deep in Yunnan, China, simple peasant parents have raised a smart boy. But life for the family has become impossible financially, so the parents take jobs in a distant city. Promising to return on the new year, they leave their only son to live on his own. Loneliness sets in and the boy stumbles upon a lost piglet. He raises the pig as a member of his family. As the new year gets closer, the boy is forced to make a difficult choice: sell the pig and make a special dinner for parents , or keep his best and only friend.
