The birth of the atomic bomb changed the world forever. In the years before the Manhattan project, a weapon of such power was not even remotely imaginable to most people on earth. And yet, with war comes new inventions. New ways of destroying the enemy. New machines to wipe out human life. The advent of nuclear weapons not only brought an end to the largest conflict in history, but also ushered in an atomic age and a defining era of "big science". However, with the world now gripped by nuclear weapons, we exist constantly on the edge of mankind's total destruction.

A filmmaker embarks on a poignant journey with his parents to the secret city where they unknowingly contributed to the creation of the first atomic bombs.

A 1954 Indian Bengali Drama Film directed by Taru Mukhopadhyay.
