He also saved his camp commandant from being killed by vengeful prisoners, and was presented with an ancestral sword for his intervention. Seventy years after the atomic bomb destroyed Nagasaki, and 20 years after MacCarthy's death, his daughter goes on an origin quest in this fascinating documentary, directed by Gerry Lennon, which was shown in Irish cinemas last year to great acclaim, and was nominated for an Ifta award earlier this year.
