Raj and Abha, a couple in their early-thirties, move into their new 2-bedroom flat in a Mumbai suburb. They are both very happy as only new home-owners can be in Mumbai. Since the flat is in a residential complex away from the bustle of the city and the main road, they both expect peace and quiet.
However, every night Raj is disturbed by strange screechy noises. They wake him several times in the nights (Abha is undisturbed though). Finally one night, Raj discovers that it is the nightwatchman blowing the whistle periodically to scare thieves away. The nightwatchman - Matthew, refers Raj to Janardhan, the new secretary of the building society, who has passed these orders to enhance security.
Raj appeals to Janardhan the next day, but meets a brick wall. Janardhan refuses to stop the whistling as according to him the safety of the community is much more important than the comfort of one individual. A society meeting is called and the whistling is replaced by the banging of the stick. But this is still loud enough to disturb Raj, so his problem continues.
Janardhan is a small time businessman and his nagging wife constantly reminds him of his failure to make it big and life passing them by. On being appointed secretary of the society, Janardhan overcompensates for his mid-life crisis by overzealously passing orders.
The tussle between Raj and Janardhan takes on serious proportions and significantly alters both their lives. The nightly disturbances lead to a domino effect which completely destroys Raj's judgement, composure, professional and personal life. His bid to salvage the situation and get his own back at Janardhan lead to a sequence of events involving Raj, Janardhan and the nightwatchman Matthew which eventually end with their lives get extraordinarily realigned at the end despite the innocuous beginnings
