Louis Pothen is a popular part-time television film critic, an artist, and a divorce lawyer who also participates in a live TV channel named "Kathrika". His wife Vasuki Iyer is a Kathakali artist, and they live together along with their school going daughter Chintha. They live away from their parents since their marriage was an inter-religious one. One day, Vasuki is raped by her two neighbours, Aryan and Sudeep, who are engineering students, and Pachai, a man who irons clothes at her building. Vasuki goes into shock after the rape. She does not confide in anyone and becomes withdrawn. Her demeanour changes as she becomes irritable and lax in her household work. She even contemplates suicide, but better sense prevails when she realises that it is her rapists who should die and not her. After a Kathakali performance, she is complemented by Jeena Bhai, the new police commissioner. Vasuki finds Jeena's phone number from Louis's mobile and calls her and narrates her ordeal. Jeena Bhai's telephonic assistance helps her kills her rapists one by one. After the deed is done, Jeena tells Vasuki that their brief friendship over the phone was over and Vasuki should never contact her again. It is later revealed that Louis was informed by Swami, a resident of a neighbouring apartment building, of his wife being raped. Swami had witnessed Vasuki being raped from his house but was old and too far away to help. He informs Louis about what he saw. Louis, through a mobile software, mimics Jeena and guides Vasuki to murder her rapists. He realizes that this was the only way that she would get absolution. Louis never reveals the truth to Vasuki and decides to keep it as a secret so that they could lead a happy married life.
In July 2015, it was reported that Mammootty and Nayantara would play an inter-caste couple in A. K. Sajan's forthcoming film. The film was reported to be initially planned with Suresh Gopi in the lead. It was also reported that Sajan initially wrote the script with Renji Panicker in mind for the lead role, with Muthumani as heroine. But after hearing the script, Renji noted that the script demands a "larger scale" production and suggested Mammootty for the lead role. As per Ranji's suggestion when Sajan approached Mammootty, the offer was immediately accepted by him. Regarding the characters, A. K. Sajan says, "Mammootty's character in the film, Louis Pothen, almost mirrors his real life personality. He's an easy-going lawyer, who is also a film critic and has a socialist leaning. However, Nayanthara's character Vasuki is diametrically opposite."
