Puneet (Ajay Devgn) and Munmun (Konkana Sen Sharma) live in Mumbai. They barely have time for themselves, so enetertaining a guest is out of the question. But the unexpected happens.

Chachaji (Paresh Rawal) enters their lives as a "guest", albeit not an ordinary one. Initially the couple was more than happy to have him around, but his villager-like lifestyle tests their patience to the maximum limit. Will his self extended stay make them throw him out?
