The storyline, set between 1925 and 1947, spans 22 of the most difficult years of the country, after the Khilafat movement, the demand for Pakistan, the communal riots, Independence and Partition, and where most films have skirted a direct negotiation of these events, Dharmputra squarely addresses them. Ashok Kumar plays a nationalist nawab who takes part in the Quit India movement. Through the plot device of a Muslim boy raised by a Hindu family, who grows up to be a rabid Hindu fundamentalist and nearly commits matricide during the Partition riots, the whole panoply of emotions and attitudes of the times are evoked, right through to the eventual reconciliation of the two families. Images such as a bridge between houses act as symbols of Hindu-Muslim unity. The last scene has the entire family, of Hindus and Muslims, standing on that bridge. One brother is a Congress nationalist and another a left-leaning figure, so the entire political spectrum is incorporated. And as Rajendra Kumar, the figure of a leading politician sings ‘Ye Kiska Lahu Hai, Kaun Mara’ (Whose blood is this, who dies?), the film raises the question of the impossibility of differentiating identities through human blood and that Hindus and Muslims are born of the same mother and tied together by the bonds of blood that constitute the nation and write its filmic story.
