Overview:

Kolkata, India, in the near future, has been badly affected by climate change and sea level rise. The floodwater has forced most people to move out of the city, turning it into a ghost town. The Sundarbans forest, just to the city's southern fringe, has also been devastated, forcing a lot of wildlife, including tigers, to move north into the shell of Kolkata. However, a few people remain in the city, wading around, looking for sustenance. A family of climate change refugees arrive in a flooded Park Street, where they are attacked by a hungry tiger. While some are killed, the rest manage to flee into a building nearby, leaving behind a blind girl who uses a raft made of plastic bottles for her conveyance. When a much larger ambush of tigers arrives on the scene, things begin to take a dark turn when both species go to extraordinary lengths to survive.
