The Last Emperor

The film opens in 1950, five years after the capture of Puyi by the Red Army when the Soviet Union entered the Pacific War in 1945 and his having been kept in their custody. In the recently established People's Republic of China, Puyi arrives as a political prisoner and war criminal at the Fushun Prison. Soon after his arrival, Puyi attempts suicide, which only renders him unconscious.
In the first of a series of flashbacks between 1950 and various prior times, Puyi relives his being summoned to the Forbidden City in 1908, aged two, by the dying Empress Dowager Cixi. With her last words, at an audience with Puyi and his father, Cixi announces that Puyi will be the new emperor. After his coronation, Puyi, frightened by his new surroundings, repeatedly expresses his wish to go home, which is denied him. Despite having scores of palace eunuchs and maids to wait on him, his only real friend is his wet nurse, who accompanied him and his father to the palace on the Empress Dowager's summons.
The next section of the film continues the series of chronological flashbacks showing Puyi's early life: from his imperial upbringing in the Forbidden City with his younger brother, Pujie, during the Republican era, his tutelage under the kindly Scotsman, Reginald Johnston and his marriage to Wanrong, to his subsequent exile in Tientsin following the Beijing Coup, his Japanese-supported puppet reign of Manchukuo, and then his capture by the Red Army â all of which are intermixed with flash-forwards portraying his prison life in the 1950s.
Under the "Communist re-education programme" for political prisoners, Puyi is coerced by his interrogators to formally renounce his forced collaboration with the Japanese invaders for war crimes during the Second Sino-Japanese War. Finally, after a heated discussion with the camp commandant and upon watching a film detailing the wartime atrocities committed by the Japanese, Puyi recants his previous stance and is considered rehabilitated by the government; he is subsequently set free in 1959.
The next section of the film shows a flash-forward to 1967 during the rise of Mao Zedong's cult of personality and the beginning of the Cultural Revolution. By now, Puyi has become a simple gardener who lives a peasant proletarian existence. On his way home from work, he happens upon a Red Guard parade, complete with children playing pentatonic music on accordions en masse and dancers who dance the rejection of landlordism by the Communists. His prison camp commander, his only friend during his incarceration, is forced to wear a dunce cap and a sandwich board bearing punitive slogans, and is one of the political prisoners now punished as an anti-revolutionary in the parade.
In the epilogue, Puyi later visits the Forbidden City as an ordinary tourist. There he meets an assertive little boy wearing the red scarf of the Pioneer Movement. The young Communist orders Puyi to step away from the throne. However, Puyi proves to the boy that he was indeed the Son of Heaven, proceeding to approach the throne. Behind it, Puyi finds a 60-year-old pet cricket that he was given by an elderly Mandarin on his coronation day and gives it to the child. Amazed by the gift, the boy turns to talk to Puyi, but the emperor has disappeared.
The film ends with a flash-forward to 1987 where a tour guide is leading a group through the palace. Stopping in front of the throne, the guide sums up Puyi's life in a few, brief sentences, concluding that he died in 1967. The picture freeze-frames on the throne and the credits roll.
