Kasoor is a 2001 Indian Hindi suspense thriller film produced under Mukesh Bhatt's Vishesh Entertainment Ltd. and directed by Vikram Bhatt. It features Aftab Shivdasani in his second Bollywood appearance and Lisa Ray in her Bollywood debut.
Plot: The film starts with the murder of Priti, wife of Shekhar (Aftab Shivdasani), a wealthy and well-known journalist. Inspector Lokhande (Ashutosh Rana) investigates the case and accuses Shekhar of the murder, saying he has enough evidence to arrest and convict him. However upon getting bail from the court, Shekhar asks his lawyer to fight his case for him however his lawyer tells him that he will not be able to fight his case because he is a corporate lawyer and only fights civil cases. He suggests Shekhar to ask Simran Bhargav (Lisa Ray), who is a very skilled criminal lawyer in his firm to fight his case.
Shekhar goes to Simran's house to convince her to take his case. Simran tells Shekhar that she'll defend him only if she is convinced that he is innocent. Simran is battling inner demons over a case in which she got a man convicted for crime he had not committed. Her guilt increases when she learns that the innocent man had committed suicide in custody.
While representing Shekhar, whom she considers innocent, Simran falls in love with him – a part of Shekhar's plan to win her trust. They end up having intimate, passionate and sensual sex. After the court declares Shekhar innocent, Simran spends the night with Shekhar at his house. The next morning, while opening his closet, she finds a typewriter hidden between sheets.
The significance of this typewriter is that there have been typed 'crank' letters sent to her office, leaving little clues that point the finger to the swimming coach Jimmy Parera (Vishwajeet Pradhan), who had an affair with Shekhar's wife. The typed letters all have a flyaway 't' on them.
Simran then comes to know that Shekhar is the real murderer. She leaves for the police station to give the typewriter she has found. Shekhar realizes this and is on the prowl to claim his next victim. In the end, Simran kills Shekhar in self-defense.
