Shortly after the outbreak of the Spanish Civil War, the Republic sent 3,000 children to Russia to protect them from domestic bombings. The first to leave were the children in the orphanages. Beatriz, the daughter of a wealthy Fascist family, whose father and brother were Falangists, becomes pregnant by a man who refuses to marry her and decides to hide her son in an orphanage in Madrid. Upon learning of the impending trip to Russia, Beatriz steals the identity of a dead Republican and volunteers to babysit. She undertakes a perilous journey, surrounded by enemies and thousands of miles from her country. On 22 June 1941, Germany invades the Soviet Union. The continuous arrival of fresh troops for the defense of Moscow hinder the journey of the Spanish. At one of these stops they are joined by Alvaro, a political commissar of the Communist Party of Spain.
