Madhoshi (2004)

Anupama leads a sheltered life until she meets Arnav, a handsome, intense man who tells her he is an undercover agent hunting dangerous enemies. Drawn into his world, she falls deeply in love, even as his behaviour grows more erratic and her family pushes her toward a more settled match. As the film goes on, Anupama has to decide what she believes about the man she loves. Madhoshi ("intoxication") was one of the films that followed Bipasha Basu and John Abraham's pairing in Jism, and it gives Priyanshu Chatterjee a key supporting role. It is part romantic thriller and part psychological drama, with a twist in the middle.
