Ishan Films P. Ltd.'s CHHAL, produced by Nitin Patil, Uday Shah and Umesh Bagul and directed by Hansal Mehta, is the story of an undercover cop who infiltrates the underworld and is caught up in a web of deceit.

Inspector Karan Menon (K.K.) is appointed on a clandestine mission by the police force to reach into the inner recesses of the mafia and pass on the information to them, which will be used to arrest criminals and prosecute them. His only contact will be Inspector Ramesh Dave (Naved Aslam), who heads the task force.

Once inside the underworld, Karan manages to reach the upper levels and meets Girish (Prashant Narayanan) and befriends him after he saves his sister Padmini (Jaya Seal) from kidnapping. Girish works for Shastri (Vallabh Vyas), who heads the gang.

Shastri plans to leave for Malaysia and lets Girish handle the operation from India, but unknown to Girish, Shastri is playing a bigger game.

Will Karan be able to get out of the web? Will Karan's identity be discovered by the underworld?
