An aspiring writer from a small town in U.P. runs away to Mumbai. He gives himself 30 days to try and prove his worth.

Hilarity ensues when a member of the Sharma family tethers between life and death as his relatives from across the country set up camp in Mumbai waiting for the inevitable that seems to have been delayed, indefinitely.

Unfolding through a course of a night in Mumbai, Kaalakaandi showcases three parallel tracks — a man who discovers he has terminal illness decides to let go of his principles and live a little; a woman involved in a hit-and-run seeks redemption and two goons must decide if they can trust each other.
