The suspicion of an alert grandmother leads to the cracking of a crime syndicate that deal in abducted children fronted by an orphanage, which is headed by a corporate.
One day, the alert Nani catches a glimpse of a nervous girl peeping from a third floor window, a house of a newly arrived childless couple. Her curiosity gets the better of her and one incident leads to another. Before long, she is convinced that there is something terribly wrong and her suspicion is proved when the first of the murder takes place; that of the maid. However, no one is ready to believe her because there is no body found. But Detective Nani has one vital clue - the white dupatta she saw near the corpse.
Joining her in the quest to crack the case is her two young grand children and her divorced daughter.
Looked at from a child's perspective, the movie passes muster. There's suspense, drama and comedy. There's also the family dog that helps in unearthing vital clues. And there's Detective Nani who, goes about her business of collecting vital clues even though many feel she is just getting on in age.
Looked at from a grown-up point of view, it could have been much better. In fact it could have gripped the audience because at the centre is an interesting tale. The narration is where the film falls flat. Director Romilla Mukherjee could have done better since she is also the writer. The acting too is of television serial standard. That's another sore point.
Of the cast, it's Ava Mukherjee as the grand old lady who keeps the proceedings alive with her cute demeanor and sharp wits. Another talent that catches the eye is the CID officer played by Ankur Nayyar. He's in the mould of Rajeev Khandelwal who made his big screen debut with the critically acclaimed Aamir.
