Bezubaan, as the name suggests, is the story of a woman (Reena Roy) who suffers silently; society and family pressures effectively stifling any protest she might have voiced. In the process, she gets blackmailed by an unscruplous photographer who has pictures of her and her lover (Raj Kiran) taken before her marriage. Reena's husband (Shashi Kapoor) is a trusting, humane person who loves his wife very much and can't understand why she needs as much money as she does. But the truth is eventually revealed and even the meek turn violent under pressure when emotions suppressed become uncontrollable. What will Reena do?
