The film revolves around Siddhant Rai (Rishi Kapoor), a wealthy, widowed architect with three hyperactive children and a brother (Tikku Talsania). The three brats go through many a governess, with orphaned Anna (Kajol) waiting at the end of the line. Anna wins the hearts of the three young children, replacing the motherless void in their lives.
In comes Shekhar (Ajay Devgan, silent and brooding as always), a petty conman/thief who woos and romances Anna. All goes well until Siddhant Rai dies, leaving behind three orphaned children and a large estate, with scheming, miserly uncles aplenty, all after Siddhant Rai´s wealth. Anna and Shekhar´s romantic world is put in jeopardy when Anna discovers that Shekhar is a crook. All is lost until Shekhar, in a grand ploy to win back the hearts of Anna and the kids, disguises himself as Raju Chacha, the children’s long lost uncle, younger brother of Siddhant Rai, back to do battle with the evil uncles.
