Arunachalam initially refuses to take up the challenge and says the videotape is enough for him and decides to return to his village to proudly say about his father. However he overhears Vishwanath, Kurain, Prathap and Kaliaperumal talking about killing Rangachari to take away all the assets. Arunachalam understands their true intention and accepts the challenge to spend Rs.30 crore in 30 days, following the rules, much to the quartet's shock. Arunachalam challenges them that he would win the challenge and expose them to the world. Nandhini is appointed as his assistant to take care of expenses.
