Kyo Kii... Main Jhuth Nahin Bolta

Raj Malhotra is a lawyer who succeeds professionally by constant lying. His persistent dishonesty infuriates his wife, who threatens to leave him if he doesn't straighten out.

Raj's son wishes that his father could not lie, and creates a sort of curse that prevents Raj from speaking anything but the truth. Raj soon finds that honesty, while sometimes vexing, yields its own rewards.
