The true tale of Irena Sendlerowa, a social worker in the Warsaw ghetto in the early 1940s, during the early days of German occupation. She is credited for saving the lives of 2500 Jewish children by gradually and quietly smuggling them to safety in small groups. While she is eventually arrested by Gestapo, imprisoned, and tortured for her actions, she refuses to reveal her network and is condemned to death. She is ultimately saved from death by other members of her organization.

This second volume focuses on Irena's activities following her incarceration, and her years long mission to locate and reunite the rescued children with their families, which led decades later to her ultimate recognition. Her attempts to locate each of their natural parents for reunion were as often heartbreaking as fulfilling. And while most of the parents had been gassed in the Holocaust, she made it her mission to help those orphaned find new homes.
