In 1843, Isabel II is declared queen of Spain with thirteen years and, the following year, makes an official visit to the Ministry of Time at the time. But the former agent of the Ministry Armando Leiva, deeply resentful of the ministry, travels to 1844 to assassinate the queen. Among the plans of Leiva is included that the mother of Isabel, María Cristina de Borbón, blame the ministry of the attack and close it. Salvador decides to send Ernesto, Alonso and Amelia to the nineteenth century to stop Leiva but the agents and Salvador himself are captured, so the ministry depends on Irene, stopped for having helped Leiva escape, and Julian, who is enjoying the company of his wife.
