Arindhum Ariyamalum

Satya (Navdeep) is an innocent Brahmin boy from Nagercoil, who comes to Chennai to study engineering. His problems start after he encounters the dreaded don Adinarayanan (Prakash Raj), who turns out to be Satya's father & Adinarayanan's short-tempered adopted son Kutty (Arya). Satya tries to stay away from them, while Adinarayanan & Kutty constantly badger him to come live with them. (Summary by iceblox)
