This is the incredible true story behind Quentin Tarantino’s film Inglourious Basterds. As a teenager, Hans Wijnberg is sent to America from Holland to escape Nazi aggression; Fred Mayer and his family flee Germany. Both enlist in the U.S. army and are recruited for ‘Operation Greenup.’ They're sent to investigate a Nazi stronghold in one of the most successful and daring missions of WWII.
