But he had to face his moment of truth. How does he face his moment of truth, and how does Gauri help Hema to go away with him, despite threats from Ajit Prasad, and what moments of truth Ajit Prasad and Hema had to face, comprise to make this movie DO NUMBER KE AMEER based on TRUTH of life the ETERNAL TRUTH & ONLY TRUTH.
