Civil engineer Shekhar lives with his wife Chitra and their two young children Arjun and Anu. Chitra delivers a third child, but the daughter is claimed to be stillborn. Two years later, Shekar and his family move to a new apartment complex. The family seems to have moved on from their grief due to the stillborn child incident and live happily. After a few altercations with the kids in the colony, Arjun and Anu are accepted by all the kids as their own. The kids are all for pulling pranks and generally causing a clamour around the apartment colony. One such constant joke, they play on a mentally disabled ex-watchman of the colony, much to the chagrin of his wife. The only tenant they are afraid of is Dennis Joseph, an ex-convict, who lives alone in one of the apartments.
