	The war starts and he is called for it. But before going on war, Kamli takes a promise from him to protect her husband, which he does. When Ram Singh asks a dying Nandu why he risked his life to save him, his last words are, "Usne Kaha Tha" [she had commanded so], giving the raison d'être(the sole or ultimate purpose of something or someone), hence the name of the film.
