Asuran

Sivasaamy (Dhanush) is a farmer from a poor, low-caste family, a quiet man who has spent his life avoiding a fight. When his teenage son kills a wealthy upper-caste man, the family runs, with Pachaiyammal (Manju Warrier) and the other children going with them. Vetrimaaran follows the pursuit, and with the dead man's relatives hunting them, Sivasaamy has to find a way to keep his hot-blooded boy alive.
