Bunty and Tanya. Two people very much in love. Quite naturally, they should get married and live happily ever after. The problem?

Bunty will do anything for love – except get married. It’s not hard to understand his phobia of marriage if one were to look at his parents, Kishen and Mala – two bickering senior citizens who are so incompatible that they are like a match made in hell even on their 33rd wedding anniversary! While the couple runs a restaurant where they serve their volatile arguments as complimentary with the food, Bunty has never really understood why his parents got married and what stops them from getting divorced.

While Bunty struggles to explain his predicament to Tanya, she is left with no other option than drag him to her grandfather, Professor Anthony Gonsalves (Randhir Kapoor), who threatens Bunty with an ultimatum – either get married or stop seeing Tanya! Unfortunately for Bunty, the ultimatum comes with a deadline of a few hours on the eve of his parents’ wedding anniversary.

But as Bunty watches helplessly, his surprise party for his parents deteriorates into yet another explosive verbal duel between Kishen and Mala before a crowd comprising of a friends and foes from the past – including former twin-voiced singer Kundan and 70s sex kitten Mona.

Desperate to save his parent’s marriage and his own love life, Bunty embarks on the most challenging journey of his life as he turns back the clock – to rewrite Kishen and Mala’s destiny and alter their disastrous arranged marriage into a romantic affair of the hearts.

In an era where he wasn’t born and caught in a family feud between Kishen’s father, Rai Bahadur, and Mala’s mother, Bholi Devi, Bunty’s future depends on not just playing Cupid and transforming his father from a wimp into an eligible bachelor and his mother from a tomboy into the epitome of feminine grace, but also coping with the inadvertent transformation of Kundan and Mona in the process – which further complicates his already complex mission!

But all’s well that ends well, as Bunty races against time to overcome the hurdles of the past for a present where he is much wiser about love and marriage – and blessed with parents who are inseparable even in their old age on their 33rd wedding anniversary!
