Sehar (2005) is an Indian Hindi language action crime drama film directed by Kabeer Kaushik, starring Arshad Warsi and Mahima Chaudhary in the lead roles with Sushant Singh and Pankaj Kapur in supporting roles. Based on real-life incidents and individuals, the film depicts organized crime in the late 1990s in the state of Uttar Pradesh, India, and how the State Police worked to tackle it. It shows the turbulent journey of Ajay Kumar, a newly appointed 31-year-old SSP of Lucknow, played by Arshad Warsi, instrumental in bringing together a group of committed police officers under the aegis of Special Task Force. The force, given with a single agenda, succeeds in challenging the might of organized crime in the Uttar Pradesh. In the process, what unfolds is the ever-changing dynamics of Uttar Pradesh's Siyaasat: railway contracts, Inter-Services Intelligence involvement, politician-Mafia-police-builder nexus, pro-activism of criminal gangs, sophisticated yet rigid red tape and criminalization of university students.
The movie is loosely based on the encounter of the notorious criminal Shiv Prakash Shukla (alias Shri Prakash Shukla) who was eliminated by the newly formed Special Task Force of the Uttar Pradesh Police. He was not only a dreaded gangster but also a connection between the underworld and the politicians.
The character of SSP Ajay Kumar is based on SSP and the then STF chief Arun Kumar, a 1985 batch IPS Officer.
