Khoei Yai Saphai Lek(2015)

Original title: เขยใหญ่ สะใภ้เล็ก

The bitter rivalry between two powerful local patriarchs could not wither the blossoming friendship between their children. But when a daughter of one house becomes the youngest daughter-in-law of the other, and a son must take his place as a son-in-law in return, an all-out local war becomes inevitable.
