Hirak Rajar Deshe (lit. 'In the country of the Diamond-King'; English title: "Kingdom of Diamonds") is an Indian Bengali dystopian fantasy musical film and a sequel to the 1969 anti-war fantasy musical Goopy Gyne Bagha Byne (and the second installment of Goopy Gyne Bagha Byne series) directed by Satyajit Ray. In the film, the musicians Goopy and Bagha (who received magical powers in the first film) travel to the kingdom of the Diamond King, to find a sinister plot at work – subjects are being brainwashed by rewriting their thoughts with rhyming slogans.
