Goopy Gyne and Bagha Byne ruled the kingdom of Shundi and got bored of enjoying the royal luxuries. They want to get back to the days of adventure they had enjoyed all their lives, but age comes in the way. They leave the kingdom in search of new experiences. Finally, they reach Anandapur and win the king's heart with their musical abilities and powers. In the court room, they meet Brahmananda Acharya, who invites Goopy and Bagha to come to Anandagarh fort. When they go to his place, he offers them a job to steal three valuable stones, making use of their miraculous powers gifted by Bhuter Raja (King of Ghosts). In return, he promises to make them 20 years younger. But he couldn't make younger anyone. He tell a lie. They steal two rare stones with the hope to become young again.
