This film is about a gang of innocent but feisty kids who lead carefree lives in Chandan Nagar colony that takes on the big bad world of politics when one of their friend’s life is endangered. It starts with an introduction to the lead actors, who live in Chandan Nagar Society. Each of the eight children has his own identity and a nickname based on these qualities. Akram is the fast bowler (Ramashankar), Encyclopedia is the mastermind (Arjun). Not only that, but their whole team has a nickname – CHILLAR PARTY. They explain that they have mainly two enemies with the ‘oversized’ neighbouring cricket team to whom they always lose, and a dog to whom they have given a name – Loose Motion, since it has a tendency to make messes. So they develop an enmity against dogs. Their hopes are shattered shortly after a boy- Fatka who was employed for washing the cars of the society, enters with his dog Bhidu. They do everything to throw the boy and his dog out, but become unsuccessful. Eventually they develop a friendship with each other as Fatka helps them by serving as the lead bowler during the match with the neighbouring cricket team. But their happiness is short-lived when a reckless politician, welfare minister Shashikant Bhide, enters their life after his personal secretary is attacked by Bhidu for hurting Fatka.
He announces that in a news telecast, all the stray dogs roaming about in residential buildings in Mumbai will be caught and terminated and gives an excuse that it is done so that Mumbai becomes safer- and declares the slogan as “Safe Mumbai and Safe Mumbaikar”. He further informs that the dog can only be saved if the society files a NO OBJECTION CERTIFICATE within 1 month. Chillar party, shocked by this, strives hard to get the NOC- wherein they have to get at least more than 50% votes of the total residents in the society i.e. 31 votes. But they manage only ten votes after 15 days.
