This documentary effectively focuses on the Allied war effort and in particular how it related to the liberation of Jews immured in concentration camps. It is narrated by some well known and popular actors (including Patrick Stewart and Whoopi Goldberg), and seeks to answer the question "Who knew about the killings, and when, and what did they do about them?" In addition to archival footage, vivid anecdotes by people who lived during the period are recounted, including one telling about an British matron who, after extending an invitation to American soldiers to come to lunch at her house, saw fit to add "no Jews, please." In response to her offer of hospitality, she was horrified to find that on the day in question six black servicemen were her guests. Protesting that there surely had been a mistake, the servicemen responded: "Colonel Cohen doesn't make mistakes."
