A few months before his death, Primo Levi meets the students of the Rignon primary school in Turin, the same one he attended as a child. From the hand of the writer, children will learn what the Holocaust was, and they will know the first-person experience of one of the survivors of the hell of Auschwitz, one of the darkest pages in the history of the 20th century.

"You know, children, when I was your age, I loved numbers… But I couldn't imagine that I would have to wear one on my arm all my life."
The comic is complemented by a detailed chronology about the life of Primo Levi, and by an expanded description of the most significant characters in his history.
