Steal a Pencil for Me(2007)

Overview:

1943, The Netherlands is under total Nazi occupation. In Amsterdam, Jack, an unassuming accountant, first meets Ina at a birthday party - a 20-year-old beauty from a wealthy diamond manufacturing family who instantly steals his heart. But Jack's pursuit of love will be complicated; he is poor and married to Manja, a flirtatious and mercurial spouse. When the Jews are being deported, the husband, the wife and the lover find themselves at the same concentration camp; actually living in the same barracks.
