Mampu watches her father struggle to keep his one screen theatre afloat, as her hometown acquires a new name, losing traces of its rich cultural past.

Allahabad is in the throes of change as a new era sets in with the city being renamed. Looking at development in the eye, an ailing Madhav Chatterjee battles to keep his decrepit single screen theatre alive. His daughter Mampu tends to her father, but finds him immersed in the past. The theatre contains within its crumbling walls an entire childhood and her most anchored friendship. Much like a river disappearing, the gentle flow of memories are held ransom by demands of the present. As the last few strands of her identity trickle out of the theatre, Mampu struggles to find a sense of belonging in her shape-shifting hometown.
