Deepak Malhotra (Parmeet Sethi) is a widower from Pune, living with his three children - Chinky, Vishu, and Gochu. He learns of the demise of his elder brother and sister in-law in a car accident, and shifts base to Mumbai, in order to look after his brother's children - Kittu and Pinky. He also takes over at Zara Hatke, the ad agency and film production house of his brother. Kittu and Pinky don't really like their uncle and their cousins living with them, and constantly devise plans to get rid of them. Even Deepak's children reciprocate, by playing tricks to give it back to their cousins. They eventually make peace. The story revolves around the children and their daily lives, which sometimes develop into comic situations.
