Poochi lives in a small hut with his grandson Kumaresan, whose parents were killed in a caste riot a few years ago. Poochi has big dreams for Kumaresan and does all kinds of work to save money to get Kumaresan into a private school.

However, once the pork and drink go down, tempers flare up, and Poochi must avoid getting caught up in the acerbic hostilities that consume his dominant caste overlords.
