"D-Day" director Nikhil Advani asserts that his film is not a regular underworld or 'bhaigiri' film, but a serious espionage thriller based on the country's intelligence agency RAW and its operations.

Actors Arjun Rampal, Irrfan and Huma Qureshi are playing RAW agents in the film.

"There is no connection to the underworld. It is about terrorism, it is about bringing back India's most wanted man. It is an espionage thriller. All three of them and Aakash Dahiya, they are spies, they are RAW agents," said the director here at the music launch of the film Sunday.

"There is no 'bhaigiri' in the film. It is about India, it is about four patriots," he added.

The film is slated for a July 19 release and it stars Rishi Kapoor in the role of an antagonist. Shruti Haasan too features in it.
