Hirak Rajar Deshe (Bengali: হীরক রাজার দেশে Hirok Rajar Deshe, lit. "in the land of the Diamond King". English title: Kingdom of Diamonds, 1980) is the sequel to 1969 film Goopy Gyne Bagha Byne and the second installment of Goopy Gyne Bagha Byne series directed by Satyajit Ray. A unique aspect of the film is that most of the dialogues exchanged by the protagonists of the film are rhyming. The only person who did not speak in rhyme was the teacher, symbolizing that though the thoughts of everybody else are bound, the teacher was a free-thinker. The film was followed by the third film of the series directed by Satyajit Ray's son, Sandip Ray.
The magically musical duo of Goopy Gyne and Bagha Byne make a comeback in this sequel, where they are invited to the court of the Hirak Raja (The Diamond King), for their musical skills. They are to perform at the kingdom's Jubilee Celebrations.
Goopy and Bagha are bored with their lives as crown princes of Shundi and Halla. They are looking for a change, which comes in the form of a chance to visit Hirak Rajya (Land of Diamonds), known for its huge diamond mines. They jocundly set out for Hirak Rajya. They are unaware of the machinations of Hirok Raja (Utpal Dutt). The king is a tyrant. Diamonds and riches get pent up in his treasuries, while his subjects starve and suffer. Those who protest are taken care of in the 'Jantarmantar', a chamber for brainwashing devised by the scientist (Santosh Dutta), who the king mocks calling as "Gobeshok Gobochondro Gyanotirtho Gyanorotno Gyanambudhi Gyanochuramoni." His ministers are mere puppets. The only enemy the king has in his land is Udayan Pandit (Soumitra Chatterjee). He is a school teacher and, more than that, he is a believer of values. The king forcefully closes his school down. Udayan flees to hide in the mountains.
Meanwhile, Goopy and Bagha are on their way to Hirok Rajya. By coincidence, they meet Udayan, who intimates them of the king's true nature. The two impress Udayan with their magical powers, who plans to use them against the tyrant. Goopy and Bagha agree. The duo then head into Hirok Rajya, where they are welcomed with grandeur. They entertain the rogue king, fooling him into believing that they think he is great. They rob the treasury (which was guarded by a tiger) using their magical music, for bribing the guards.
The king has his tricks, too. He captures Udayan and all his students, and takes them to the Jantarmantar for brainwashing. But Goopy Bagha have already reached there using their magical powers. They have also bribed the Gobeshok onto their side, with the guards. On reaching the laboratory, the king and his ministers are stunned magically by Goopy's singing and then pushed into the Brainwashing machine. After the king is brainwashed he turns to the good side, he then along with the villagers pull down his own statue situated at the center of the village, and everything goes back to normal in the land of hirak raja.Producer: Government of West Bengal

Sandip Ray, son of director Satyajit Ray directed another sequel named Goopy Bagha Phire Elo. The film released twelve years after release of Hirak Rajar Deshe.
Sandip Ray want to make another sequel to this series. He had received many request to make the fourth Goopy - Bagha movie. Ray said to The Times of India about the plot of fourth film: "Making a Goopy Bagha movie without Tapen and Rabi is unthinkable. The only way I can do a fourth is by taking the story forward and introducing Goopy and Bagha's sons," he said. The idea to weave a story around the next generation came from a line from the introductory song 'Mora dujonai rajar jamai in 'Hirak Rajar Deshe' — "aar ache polapan, ek khan ek khan... (we have one child each)".
