The one-minute video opens with Jawaharlal Nehru's famous Tryst with Destiny speech. Boman Irani's voiceover takes over from there and reminds us of some glorious moments of independent India. One of them falls in May 1988, when India tested fusion bombs in Pokhran, Rajasthan.

Produced by JA Entertainment, KriArj Entertainment, Zee Studios and Kyta Productions, the film is written by Saiwyn Quadras, Sanyuktha Chawla Shaikh, and Abhishek Sharma.

It will hit the theatres on May 25
