Rukhsana Jamal and Anwar had been married for several years, and have two daughters, Tehzeeb and Nazeen, from this marriage. Anwar goes through a period of mental instability and depression, which ends in his committing suicide by shooting himself dead. Years later Tehzeeb and Nazeen have both grown up. Tehzeeb has married Salim Mirza, while Nazneen is mentally unstable. Their fairly smooth lifestyle changes abruptly when Tehzeeb finds out that Salim is having an affair with Sheena Roy; and Nazneen comes across a loaded revolver.
