Ranbeer Talwar (Saif Ali Khan), one of the country's top industrialists, is a loner, not by choice, but because he lost everyone he ever loved. He is now faced with a very peculiar and uncomfortable situation. In a rare and landmark court verdict, he is to look after 4 orphan children.

The orphans hate him and want revenge from him. The children do not want to live with a man they hate; he too cannot face them or look them in the eye for certain reasons. Their life together is very unhappy, one day they pray to God for help and he does help them. He sends his most mischievous, childlike, lovable angel to the rescue, with a mission to bring Ranbeer and the kids together.

Geeta (Rani Mukerji) comes bicycling down a rainbow… and bursts into Ranbeer's house as the self-proclaimed new nanny. And then starts the roller coaster ride of fun, emotions, magic and love. An angel who doesn't know what love is.
A man who always lost love. Four orphans who need love.

All come together to bring you a film with fun, excitement, masti, tears, magic and love
Truly…
…Thoda Pyaar, Thoda Magic!
