Kazi Nazrul Islam was called a 'dhumketu' or comet by Rabindranath Tagore for his rebellious style of writing. The film traces the life of Kazi Nazrul Islam, the sources of his inspiration and how his poetry came to reflect his fiery and rebellious spirit. Nazrul was deeply inspired by the Bolshevik revolution, the communist ideology and in line with his political thought processes, he wrote a poem titled "Autobiography of a Vagabond". His spirit of rebellion for change made him join the army during the World War I. However, during this time, he learnt Persian and Arabic and brought the ghazal genre of North Indian music to Bengal. Nazrul became a prolific song writer with over 3000 songs to his credit.
