"The film is not a biopic. It has been inspired by the incident but not based on that particular incident. The characters are imaginative and I wanted to show the state-of-mind or the emotion that might have driven them to do such a crime, " Verma told reporters at the first look of the film here at Cinemax Versova.
Grover was stabbed to death by former Navy officer and Susairaj's boyfriend Emile Jerome in her flat. The actress was Thursday convicted of destroying evidence.
