Vijay Salgaonkar (Ajay Devgn) is an orphan who dropped out of school after his 4th grade. Now he is a contented successful businessman running a cable TV service called Mirage Cable in Pondolem, Goa. He is married to Nandini (Shriya Saran), and they have two daughters, Anju, his adopted daughter (Ishita Dutta), a class twelve student, and Anu, a class six student. His only interest apart from his family is watching films. He spends most of his time in front of the TV in his small office. He has gained much fame in his rural area for helping people out with the help of methods he watched from films.
During a nature camp, a hidden cell phone camera records Anju removing her clothes and showering in the bathroom. The culprit, Sam aka Sameer (Rishabh Chaddha), is the son of Inspector General of Goa Police, Meera Deshmukh (Tabu). Sam comes to blackmail Anju for sexual favors when Vijay is not home. Nandini intervenes and pleads with Sam to leave their family alone, but Sam refuses to leave them or delete the video clip unless his sexual demand is fulfilled. In an attempt to break the offending cell phone, Anju takes a swing at Sam with a lead pipe, but she strikes him in the head instead, killing him immediately. They hide his body in a compost pit, which is witnessed by Anu. In the morning, when Vijay returns from work, Nandini tells Vijay about the incident and he devises a way to save his family from the police. He removes the broken cell phone and disposes of Sam’s car, which is seen by the corrupt Sub-Inspector Laxmikant Gaitonde (Kamlesh Sawant), who has a grudge against Vijay. The next day, Vijay takes his family out on a trip to Panjim, where they visit an Ashram, watch a movie, and eat at a restaurant. Meera, realizing that her son has gone missing, starts an investigation.
After a preliminary investigation, Meera calls Vijay and family for questioning. Having predicted that the police would come calling eventually, Vijay coaches his family on how to face the interrogations without raising suspicion. When questioned individually, the family sticks to their individual stories and the police are unable to find a crack in their alibis. Vijay produces bus tickets, movie tickets, lodging and restaurant bills as proof for the family’s visit to Panaji. Meera questions the owners of the establishments they have been to and their statements prove Vijay’s alibi. Meera realizes that on the day of the incident, Vijay had taken the tickets and the bill, made acquaintance with the owners and had gone for the trip with his family the next day, thus proving his alibi and making the owners unwittingly tell the lie.
