Treeless Mountain (2008)

What is the nature of childhood resilience? Sisters Jin and Bin, ages 6 and 3, live with their mother. Jin likes school and does well. One day, their mother leaves the girls with their father's sister, a woman they do not know. The mother seeks a reconciliation with their father. She leaves them a plastic piggy bank, promising to return when the bank is full. The girls scrub and clean for their aunt, a tippler who's often cranky and complaining. She gives them a few coins for their work. They earn more money catching, grilling, and selling grasshoppers. They miss their mother. The bank fills. They watch for her from a mound of dirt. Will she return? Will stoic faces give way to a smile?
