In Mumbai, once an island city connected by the sea, modern bridges and land reclamation have reshaped its landscape, disrupting the lives of its original communities. Sundari follows the myth of a legendary ferryboat, once the heart of connectivity, who guided people across creeks long before bridges existed. Now, Sundari lives on only in songs and stories, her memory overshadowed by urbanisation. Through the perspectives of a woman recounting Sundari’s tale, an ageing ferry operator who runs the Versova-Madh ferry, and a young child witnessing the changes, the film explores how progress, while practical, has disconnected a community bound by tradition and the sea.
