Aan: Men at Work

Crime is at its highest peak in Mumbai with it split in three ways. Gautam Walia, a ruthless businessman (Jackie Shroff) has one-third, Manik Rao, the Home Minister (Manoj Joshi) has one-third and Yusuf Pathan, a big-time goon (Irrfan Khan) has a third of the territory. The trio warns Raghu Shetty not to interfere with their business. Raghu pays no heed to their warning and ambushes Walia at a horse derby. Walia is alive, but Pathan kills Shetty's man who carried on the hit. Shetty is then jailed. The crime rate rises with more smuggling, trading and illegal activities soaring. Meanwhile, the Detection Unit cops of the Mumbai Crime Branch work constantly to stop this.[1][2][3][4][5]

Senior Inspector Vikram Singh (Shatrughan Sinha), who was a hero once upon a time in the crime department, now tends to handle the easy jobs. Inspector Appa Kadam Naik (Sunil Shetty) is an encounter specialist who goes after the henchmen instead of the bosses; he is married to Janki (Preeti Jhangiani) and they have a son named Rahul. Head Constable Khaled Ansari (Paresh Rawal) is a happy-go-lucky cop and chews paan (betel leaf) all the time. Kelkar (Ajinkya Deo) is another cop who talks on the phone all the time. The four men's and the whole CBI's fate changes with the arrival of their new boss.

DCP Hari Om Patnaik (Akshay Kumar) arrives and realizes that the other cops are not serious and that no one is following the rules and regulations. Om has a girlfriend, Kiran (Lara Dutta), whom he promises to marry. He is hesitant about his promotion as he thinks that this promotion is done deliberately to kick him out, but he learns to accept it. He witnesses the way the others treat the henchmen and orders them to be released. But during an encounter at a bar, the henchmen kill Khaled, making the policemen seek revenge.

He decides to join Om and Appa and help him clear the city starting with Yusuf Pathan's younger brother, Baba "Yeda" Pathan (Rahul Dev) by killing him. After that, they arrest Yusuf Pathan, which puts a halt to small-time criminal activities in Mumbai. Simultaneously, Raghu Shetty replaces Pathan to run the illegal businesses which Pathan was handling. During the climax, Appa dies in a trap set by Kelkar. Vikram and Om track Raghu Shetty and a hawala trader named Hirachand Mehta at the Flying Club with the help of a tip given by Roshni Varma (Raveena Tandon), Walia's keep to Vikram. The police try to block the plane at the runway, but to no use. Finally, Hari damages the left wing and the back engine of the plane with a helicopter. The plane crashes into a hangar. Shetty and his goons try to escape, but are killed. Vikram kills Shetty. Hirachand is arrested and Kelkar's corrupt actions are caught by Vikram and Hari. If left alive, he will be bailed out by the lawyers, so Vikram shoots him.

The arguments in the court are in the favour of Walia and his men. During the break, Vikram and Hari threaten the corrupt judge to change his judgement. The judgement is in favour of the police and the case is closed. DCP Khurrana, Om and Vikram walk out of the courtroom happily. Hari says that Mumbai is crime free. Vikram then shows a list of gangsters that had to be encountered by Appaa, to which Hari agrees. He then meets Kiran who says that she is proud of him.
