Albrecht Weinberg is 99 and one of the last living survivors of the Holocaust. Born in 1925 in East Frisia, northern Germany, he watched his family's life unravel after Hitler took power in 1933; his parents Alfred and Flora were murdered in Auschwitz. Weinberg survived and spent six decades in the United States before returning to Germany in 2012, the country whose language and streets he is still learning to live with again. The film follows him and Gerda Dänekas, his former nurse and now roommate and closest friend, as they visit schools and memorial sites, give speeches, and talk to journalists about what he lived through. Cameras catch students photographing the concentration camp tattoo still on his arm and asking him questions their grandparents might not have. Amid rising antisemitic incidents and right-wing extremism in Germany, the two describe why they keep doing this work even as Weinberg's health declines, with Gerda increasingly carrying the responsibility of telling his story forward.
