White Sheep in the Car

Zhang Shulin, unable to repay a crushing loan-shark debt, is buried alive deep in the desert by his creditor. He is dug out by Old Yang, a shepherd who happened to be looking for a lost sheep - but rescue comes at a price, barged up from 80,000 to 100,000 yuan. When their truck breaks down on the way out and the exhausted Old Yang dozes off, leaving Zhang at the wheel, he wakes to find Zhang gone - and what he discovers next is the secret Zhang was carrying.
