Alfred Nakache, a Jewish child from Constantine, never imagined that he would one day swim for France at the Olympic Games in Berlin in 1936, nor than he would achieve a world record, as he did in 1941. As a child he was petrified of the water and yet, somehow, through sheer willpower and determination, he rose to become one of the very best swimmers in the world. That was until 1943, when he was banned from the pool - and in the same year, deported and sent to Auschwitz.

Not knowing if he would ever see his wife and daughter again, Alfred battled on, through the humiliation and the pain, even defying the guards by swimming in the water reserves of Auschwitz. Somehow - miraculously - he survived, swimming every day until the end of his life.
