After the death of his wife, Gurupada Mitter, an advocate, has not been at peace. He and his daughter Buchki meet Birinchi. Birinchi Baba claims to be ageless. He tells stories from the past; his arguments with 'Pluto' about time, how he taught E=mc2 to Einstein, and was on first-name terms with Jesus and Buddha. Birinchi Baba has a growing band of rich devotees and Gurupada decides to patronise the holy man and become his disciple. Daughter Buchki is disappointed with her lover Satya. To teach him a lesson, she tells Satya that she is going to leave him and become a disciple of Birinchi Baba. Satya turns to his friend Nibaran for his help, but it doesn't take him long to realise that Birinchi Baba is a fraud.
