Old Beast (2017)

Lao Yang is an Erdosian businessman well in his 60s. He was broke years ago due to local economy decline. One day, he misappropriates a sum of money his children gathered for his wife's surgery. The children hold him in custody, forcing him to return it back. Lao Yang, outraged, takes them to court - It appears to be a reckless choice, which kicked off the whole family tragedy.
