One of the most striking aspects of "Atithi Tum Kab Jaoge" is its narrative structure. The film uses a non-linear narrative, jumping back and forth in time. This structure adds to the sense of urgency and impermanence, mirroring Siddharth's own disjointed and fragmented thoughts.
The story revolves around a modern Mumbai-based couple, (Ajay Devgn), a scriptwriter, and his interior-designer wife Munmun (Konkona Sen Sharma). Their peaceful, busy lives in a high-rise Goregaon apartment are turned upside down when an uninvited distant relative, Lambodar Chacha (Paresh Rawal), arrives from Gorakhpur. ajay devgan atithi tum kab jaoge
