Mughal emperor Humayun (Ashok Kumar). Advocating communal harmony, a policy prompted by contemporary developments, the film stresses the friendship between the victorious Babar (Nawaz) and the defeated Rajputs; he asks the Rajkumari (Veena), daughter of the slain Rajput King, to assume her father's throne and to regard Babar as a father. In the latter part the story, Humayun sacrifices his kingdom to save the Rajkumari. Hamida Bano (Nargis) is a commoner with whom Humayun falls in love, but who turns down his offer of marriage claiming that women, for all kings, are mere playthings.
