At this moment, Hemkanti is a man without memory - he cannot recognize anyone. It is as if someone is erasing everything from his brain like erasing a slate. Some lines of poetry, some notes of songs, some fragments of scenes are coming back to his mind like a broken record. He recently failed to commit suicide, and this amnesia is the result. He was involved in the Naxalite movement of the seventies. Five years ago, former Naxalite activist Varun Ghoshdastidar was killed in Purulia. Was it his companion Hemkanti who killed him that day? Hemkanti is trying to return to the light from a oblivion that has accumulated like a dense fog. Can the person close to him, Joy, be that light? Is the political faith that Hemkanti once considered the light of liberation, the same light that exists in today's Maoist movement? While walking on the road to Purulia with one of the Maoists, Joy and Hemkanti discover a truth!
