‘Kadavu’ is a story about a fisherman named Selvan, his wife Chellama and their life after a factory is set up near their shanty town. This story is loosely based on events that have occurred around the fishermen community of Tamil Nadu. The fishermen face innumerable hurdles like unexplained evacuation without resettlement, the rise in the number of thermal plants in north Chennai expelling untreated waste into the ocean causing a staggering drop in the quantity and quality of fish. Not only does this directly affect the livelihood of the fishermen but also keeping the larger picture in mind paints a daunting future.
