Atithi Tum Kab Jaoge?

Lambodar Chacha crashes Puneet's comfortable life by appearing at the Goregaon high-rise and slapping the guard, instantly interrupting the morning routine. He proclaims himself the head of the household and issues a string of unreasonable demands. The family realizes their quiet life will never be the same again.

Lambodar imposes bizarre rules: early-morning gargling, heavy meals, and a loud, public farr that rattles the house. He pressures the maid to quit and keeps pestering Puneet with constant attention, even inviting strangers as 'new friends'. The tense atmosphere makes normalcy feel increasingly elusive.

Ayush seems oddly delighted by the larger-than-life presence, treating the chaos as a game rather than a threat. Puneet and Munmun struggle to protect a sense of routine for their son while Lambodar's antics invade every corner of the home. Ayush's reaction underscores how the elder's invasion affects everyone.

Puneet takes Lambodar to his film set in hopes of placating him, hoping to channel his energy into fame. Lambodar pesters Kaalia of Sholay, urging him to recite a famous line, creating tension on set. The uneasy energy foreshadows how devotion can trigger dangerous consequences.

Kaalia finally speaks the word two, provoking the bomb operator to explode the mansion early. Director Ranjeet Taneja fires Puneet for the incident, while Puneet defends Lambodar, arguing that his uncle's devotion deserved respect. The event marks a turning point in Puneet's career and in his loyalty to family.

The couple stages a fake relative's death to lure him away, hoping to reclaim their life. The ruse backfires when the 'relative' is arrested after Lambodar sees through the ploy. The plan exposes the depths to which Puneet will go to protect his family.

Munmun engineers a Delhi trip to separate Lambodar from the home. The plan backfires as Lambodar refuses to leave and even jumps off the train to return to their flat. The family realizes a clean break might be impossible.

A night in a hotel with Ayush ends in a police raid that wrongly brands Puneet as molesting Munmun. The humiliation deepens the crisis and pushes the family toward drastic measures to salvage dignity. The incident convinces them they need outside help.

Desperate, they hire a local don to scare Lambodar away, but the plan backfires when the don instead brings Lambodar back to the flat. The emotional toll becomes heavier as the family realizes Lambodar's presence may be inescapable. The don's intervention paradoxically gives Lambodar a brief sense of safety.

Time passes and Puneet is welcomed back to work as Taneja apologizes for underestimating his bravery. A twist of fate helps Puneet reclaim his repossessed car thanks to a tie between Lambodar and a bank manager. The family begins to see Lambodar's influence as protective rather than intrusive.

With Lambodar's guidance, Ayush's schooling improves and the family begins appreciating elder guidance. Puneet and Munmun start embracing the value brought by a larger family dynamic. The atmosphere gains warmth as they adjust to the changes.

During Ganesh Chaturthi immersion at Juhu Beach, Lambodar goes missing amid a stampede. Puneet spends the night in a hospital fearing the worst, then returns home to find him alive. The scare tests the family's bonds and resilience.
