A woman falls for a charming and mysterious businessman. The whirlwind romance turns sour when she is framed for his underworld crimes. Now, finally out of prison she is ready for sweet revenge.

London-based Crystal Chaurasia convinces the International Film Commission to authorize a documentary on Bollywood's yesteryear mega-actor, Karan Kumar. She travels with her photographer Jeremy to Mumbai and not only gets to meet the legendary actor but also his publicity-shy son Rahul and his alcoholic, reclusive former-actress wife Mandira. It is here Crystal will be drawn into continuing her documentary in London where she will witness the making of Karan's next movie 'Dhak Dhak' in which he decides to not only produce and direct but also hilariously play the role of a college student.
