So what's the movie about ? There is this rich guy from a Gajner Palace in Rajasthan, who is a rich and successful industrialist. He comes to Bombay for a convention, with plans for doing what so many other people in Rajasthan have done - convert his palace into a posh heritage resort. However, being a young man, he hires from an escort service, and gets Jia Rao (played by Minissha Lamba), who does not exactly do great service to the work of an escort. He teaches her how to be an escort, and also falls in love with her (shades of Pretty Woman, maybe). They marry, and she comes back to his palace in Rajasthan. And that is where the inspiration from Rebecca happens.
The caretaker is this lady Koena Mitra, and how along with other members of the staff, keep on referring to the first wife of the industrialist, to the point that it starts to bother Jia. Jia decides to convert herself into the proper wife, and becomes more and more like the first wife, but this also bothers her husband who did not want his second wife to become like the first wife. And then, Vikram (played by Dino Morea), the rich industrialist, is accused of the murder of his first wife, things get more complicated. And then the body of his first wife gets found in the desert. What does all this lead to ? Is Jia herself in danger ? Watch the movie.
