During World War II, the icy Kazakh steppe was home to Spassk99, a Soviet-era labour camp into which the URSS would throw the enemies of the people. Amongst them were Spaniards from opposing sides: republican soldiers trained by the URSS, jailed on wanting to leave Russia at the end of the war in Spain, and volunteers with the Blue Division, captured after fighting with the Nazis in Leningrad. Natural enemies who must put their ideological differences to one side and join forces.
