Benazir(1964)

Sibling rivalry abounds in this film about two privileged brothers, Anwar and Nawab, and the women who come between them. Nawab, although a married man and father, engages in frequent secret rendezvous with his mistress, Benazir. Meanwhile, Anwar declares his love for a woman named Shahida, whom he desires to wed. So when Nawab witnesses Anwar in the arms of the lovely Benazir, he's outraged -- and puzzled -- by the brotherly betrayal.
