Mukundan Menon (Jayaram) runs a newspaper called Kerala Today. He is a normal husband who loves his wife Krishnendu (Bhavana) a lot, but she is too possessive about him. She thinks he is not very expressive about his feelings, and is always worried that he might one day fall for some other beautiful girl.

John Mathai (Jayasurya) is a photographer in Mukundan's publication. He was neither interested in girls nor keen to get married until he met Sereena (Vandana).

Rahul (Indrajith) is just the opposite. He is extremely romantic and never comes home without some cute gifts for his wife, Shreya (Samvrutha Sunil). But she doesn't know that, behind her back, her darling husband is dying to flirt with every woman that he sees.

It is into the lives of these three couples that a bar singer, Diana (Rima Kallingal), arrives and things take some interesting turns. Diana is seeking to take revenge on Mukundan Menon since it was on his article in Kerala Today that the Maharashtra court took as a petition and then banned the bar girls in Maharashtra thus ruining Diana's profession.

Diana forcibly comes to Mukundan Menon's house one day with her evil intentions and that catches the eyes of Krishnendu. To escape from trouble, Mukundan Menon says that she is the wife of John. Later, when John, Mukundan and Rahul were talking about John's marriage proposal to Serena's dad, Diana comes there by accident and there Rahul says that she is Mukundan's wife and she is mentally imbalanced. So now Krishnendu and Shreya thinks Diana is John's wife and John's real wife Serneena believes that Diana is Mukundan's wife. At one time, all these people come together at Malaysia for a vacation and that leads to a lot of confusion among the wives and others. What happens next forms the rest of the story.

For the first time in the Malayalam film industry, a criminal case was filed under the Copyright Act, 1957, against the alleged copying of the script of the Hindi film No Entry, frame to frame. In the criminal case filed before the Judicial First class Magistrate's Court in Trivandrum, the producer, director, writer and artists Jayaram, Jayasurya, Bhavana, Reema Kallungal, and Samwrutha Sunil were the accused. The artists, according to the complainant, were offenders for abetting the crime. On 23 March 2012, the Court took the complaint to the file and proceeded with it. The complainant alleged that the script of the movie was a scene by scene blind copy of the Hindi movie. The alleged offence, if proved, would attract a minimum sentence of six months that may go up to two years and fine, as provided under the Copyright Act.

Jayaram courted controversy during a promotional interview for the movie by describing a domestic worker as a "dark, fat, buffalo-like Tamil woman", following which various organisations and activists demanded an unconditional apology from him. Jayaram said this when he was asked whether his wife doubts him in the way Jayaram's character was doubted by his wife in the movie. Jayaram's house in Chennai was attacked by Tamil activists and the actor deeply regretted his comments.
