Atithi Bhooto Bhava (The Guest is a Ghost) begins in Mathura in 1975. An elderly Sikh man is giving the young Sikh Makhan Singh advice to follow his heart. Makhan’s heart leads to Manju, but this inter-faith romance will have to be realised in another lifetime.
In 2021, the elderly gent has been reincarnated as Shrikant (Pratik Gandhi), a stand-up comedian who bases his act on his frequent squabbles with his live-in girlfriend Netra (Sharmin Segal). Wary of marriage, inconsiderate towards Netra and unwilling to own up to his errors, Shrikant has a life-altering encounter with Makhan’s ghost, who is still hanging around waiting to be re-united with Manju.
