Super Nani is the story of Bharti Bhatia (Rekha) whose every waking hour is devoted to looking after the smallest need and praying for the betterment of her family comprising of her corporate czar husband (Randhir Kapoor), a son who is a wannabe stock market bull, a daughter-in-law who aspires to be the next soap-opera queen and a daughter with ultra modern values. She selflessly performs her duties only to get ridiculed, humiliated and treated like a door-mat by her family.
An exciting tale begins when Mann pays a surprise visit to his Nani, Bharti Bhatia, in India. Opposite to his expectations of seeing a strong lady who holds command in life, he sees a soft and dormant lady who is commanded by all. This annoys him. So he decides to make his Nani`s sad boring life turn into a fun roller coaster ride.
