In the Bengali language, 'Bede' means a caste or group of people who make their living with the help of snakes they capture. They entertain audiences through their unique skill in making snakes dance in a mesmerised fashion to the tune of their flutes. Joytsna (Anju Ghose) is a girl from this community.
One day, a poisonous snake bites the foot of a local prince. A bede is called to cure the prince. He sees the wound and declares that only Jyotsna can extract the poison from the prince's blood. The king calls Jyotsna and asks her to save his son, in exchange for which he agrees to give her anything she wants. Jyotsna cures the prince but becomes ill in the process.
After her mother and the queen pray for her, she recovers and demands the hand of the prince as her reward, but the king balks. When the prince, now recovered, comes to know of everything that has transpired, he falls in love with Jyotsna. After a long tug-of-war, the couple persuade the king to consent to their union and they marry.
