Adaptation of Melissa Muller's biography of Anne Frank, documenting the Holocaust victim's life from her happy childhood in pre-war Frankfurt to the years she and her family hid in an Amsterdam attic to her final days at the Bergen-Belsen concentration camp in early 1945. The movie also delves into the challenges and risks Miep Gies and her colleagues faced harboring Jews for over two years within a bustling office building. The name of the Franks' betrayers is also revealed. After the Gestapo raided the annex, the Franks traveled to numerous concentration camps, where the family and friends were separated. In the months that followed, all of them died in the camps except for Otto Frank, who returned to Amsterdam after the war ended. At that time Miep gave him Anne's diary, which she had retrieved in hopes of returning it to Anne.
