Starring Nana Patekar, the movie is produced by Alumbra Entertainment and Eros International.
Ram Gopal Varma and the producers were present for the launch of the trailer.
The two minute long trailer provides an insight of 26/11, when Pakistan-trained terrorists held Mumbai hostage for 60 hours spreading terror in the city.
The promo hits hard and Ram Gopal Varma's camera angles provide an edge to it while the shlok and the background score give goosebumps each time you watch the trailer, the producers said.
Producer Parag Sanghavi said, "The film is a tribute to the sentiments of the people of India and especially to the heroes and victims of 26/11."
Ram Gopal Varma said that the movie gives a soulful insight as an "emotional interpretation of the actual story" behind the attacks.
There is lot of curiosity about the movie and people are particularly looking forward to Nana Patekar's role, the makers said.
The newly-released trailer offers a glimpse of what happened during those 60 long hours when Mumbai was held hostage.
