The film is adapted from a true story. In the early 1940s, the Soviet Union implemented a dictatorship in Poland. The authorities arrested many Polish officers and government officials and sent them to concentration camps for reeducation through labor. There, they suffered inhuman torture and. Unable to bear the torture and to survive, Janusz, Smith and five other political prisoners managed to escape from the concentration camp and embarked on a journey back to the civilized world and the free world. On the way, they met a Polish girl named Elena. The helpless girl joined their escape team. Along the way, they encountered sufferings such as hunger, ice and snow, storms, etc. But these did not become obstacles to their progress. After escaping from the concentration camp, they walked south, through Mongolia, through the Gobi Desert, through Tibet and over the Himalayas, and finally reached India, which belonged to the Commonwealth at the time. Although they returned to the civilized world, the cost of this journey was painful. Three of the seven people who escaped from the concentration camp died, and the Polish girl they met on the road also died. Behind the Scenes: Searching for the Historical Truth In order to implement dictatorship at home, the Soviet government set up many prisoner-of-war camps and labor camps in its own country and in the occupied countries. The Russian abbreviation for the management department of this labor punishment camp is Gulag. Over time, the word Gulag has become a broad word, referring to the entire Soviet labor reform system. The starting point of the film's story is such a Gulag, which is adapted from the memoirs of Slawomir Ravich. This memoir records the story of how he was captured by the army and sent to a concentration camp after Poland was occupied by the Soviet Union, and then managed to escape with several companions. In 1956, Ravich, who escaped death, dictated this memoir titled "The Long Road". Although there is no human or material evidence to prove the authenticity of the history he told, this memoir full of adventure, search, faith, and hostility and hatred of the Soviet regime at the time still caused a sensation in the Western world. As the name "The Long Road" suggests, this memoir is almost entirely about stories on the road - in 1940, Ravitz escaped from a concentration camp in Siberia. After walking 6,437 kilometers with his companions, the few remaining people came to India. In 2006, the BBC made a documentary about Ravitz and his journey, hoping to find some evidence of the real existence of this escape. It was this documentary of textual research that made Australian director Peter Weir know the story of Ravitz for the first time. This story has been lingering in Peter Weir's mind, and gradually formed the idea of making a movie. Will said: This is an excellent story about human endurance and courage. It not only has characters, flesh and blood, but also history. How much pain and torture can humans endure in order to survive? No one knows, and this story just gives us such a sample. Before I decide to make a film, I always have to do some research on the story to be told in the film.
