Civil engineer Shekhar lives with his wife Chitra and their two young children Arjun and Anu. Chitra delivers her 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 clamor 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 an ex-convict, who lives alone in one of the apartments.
