Nanchenkotta, a fictional place on the Kerala-Tamil Nadu border, is ruled by Amarnath, the leader of DYP, a political party.

Amarnath threatens and tortures the people to keep them under control, which leads many residents to leave the land and live in neighbouring places.

Nenchenkotta is filled with goons under Amarnath's command and DYP is also involved in illegal businesses like gun production.

SI Vyshakan, the in-charge of Nanchenkotta, commits suicide after his daughter criticises him for his inability to take action in Lakshmanan's case.

Amarnath is forced to kill Appu to end his suffering and swears to exact revenge against K. Sangeetha refuses to become the next candidate and leaves for Hyderabad after a cop threatens her.

K secretly leaves Nenchenkotta and arrives at an unknown place in Tamil Nadu to restore peace and order.
