 Spunky, independent 75 year old Naani is on her way back home from her daily morning walk. She looks up to see a strange little girl peeping from the window of an apartment belonging to a newly-arrived couple. Naani s curiosity is aroused, plunging her into a full-blown murder mystery where some neighbors will come to her aid, some will be indifferent and some will prove to be very dangerous. When the CID dismisses Naani s case due to lack of hard evidence, she turns into a detective. She uses her homespun wisdom to solve the mystery in classic "whodunit" style. Naani s eccentric methods of investigation lead to a series of quirky, often humorous incidents. Along for the ride are a team of unlikely deputies - her dog Bruno, 2 inquisitive little grandchildren Nakul and Anjali, her divorced daughter Priya, teenagers Neeti and Rohan, and the elderly Mr.Pal who serves as Naani s binocular-toting ground floor spy. Clue after clue leads Naani to a racket where the stakes are high, the criminals ruthless, and their leader, very powerful. As she gets too close to their trail, she endangers herself. But Naani & Co. rise to the occasion with some sharp thinking and heroic derring-do. They win the day with a little help from the CID. Naani s dogged mission to save one terrified little girl forms the emotional spine of the film. Yet it s an adventure that touches the lives of all the homemade detectives involved. Little Nakul wins the respect of the real CID, the two squabbling teens fall in love, Naani s divorced daughter and the dashing CID Inspector share a whiff of romance and old Mr. Pal finds a renewed energy and interest in life. "Detective Naani" has all the ingredients of one s favorite movie recipe - suspense, thrills and emotions garnished with liberal lashings of humor, leaving a pretty good taste in the viewer s mouth.
