Sudha Mishra (Maasiji) who is a 67 years old, divorced and grumpy woman with enormous energy and the ability to live in the present has just come back to her home in Vasant Kunj, New Delhi. She is a mother to a confused and angry young man who has given up a career in television direction and her divorced husband is a playboy in L.A .
While she was away, Sumit, her niece's fiance was given the responsibility to take care of the house and was clearly instructed to feed the fish & water the plants. His marriage was hinging on this.
At the end of the holiday when Sudha reaches her quaint house and starts it's inspection with detective accuracy. Had the fish been fed? Had her plants been watered? She reaches the alcove with her beloved crystal fish bowl and collection of money plants. Everything seems to be in order but is it? As she opens her bedroom door she is taken aback by a woman rushing past her.
Sumit had thrown the helluva party for all his friends at Sudha's house and broken all the rules as instructed by her and also handed over the house to an eloping couple, who then handed it over to a miscreant property broker. The house is then taken over by a Haryanvi Jaat who is a cross dressing Kathak Dancer, followed by a tribal family from Mizoram.
What ensues is a recap of the events that took place beginning from when Sudha left her house in Sumit's hands. The mystery unravels almost as a game of Chinese Whisper.
