Plot: A CBI officer goes in search of a ruthless serial killer. Things get worse when the murderer targets the former and her family. The mood and premise of this thriller flick – set against Bangalore, a psycho killer is having a whale of a time by finishing off people in his list. The hero (or heroine), Anjali Vikramadityan (Nayanthara), a CBI officer, is introduced quickly and her first shot has her in a serious mission. We hardly know her details or plans behind the mission, but this fast-paced narration lights up the mood interestingly. In no time, the killer’s case becomes a sensational one in the city. In a press meet organised by a few top CBI officials, he himself sends messages to them and the journos that he is Rudra, the notorious killer, who the police department claimed to have killed five years ago.
