Argentine-Israeli journalist Shlomo Slutzky meets Argentine-Dutch journalist Mariano Slutzky, who turns out to be the son of Sami, Shlomo's cousin, a doctor imprisoned in 1968 for his participation in the guerrilla movement and disappeared by the civil-military dictatorship in 1977. Mariano and his sister Alejandra have few memories of him: some letters and drawings made in prison, through which he sought to educate them for the new times to come. Mariano accuses his relatives of abandoning them. Shlomo searches for these relatives to admit their lack of commitment and Mariano's forgiveness, but the scars of the past are difficult to overcome.
