In 1939, with great fanfare, the Nazis placed hundreds of Jewish fugitives from all walks of life in a luxury passenger ship and took them to Havana, Cuba. However, when the ship arrived at the port of Havana, the Cuban government refused entry to Jewish passengers on board in accordance with the country's strict immigration policy. In fact, the Nazis had expected this result for a long time, and that was exactly what they wanted. When the exiles left Havana, the German government could prove that Jews were the most unpopular race in the world, thus finding a reasonable excuse for Hitler's policy of ethnic cleansing. Some people think that the implication of the film is chilling, but the end of "the Sea of bitterness" still gives a glimmer of hope: the subtitles tell us that most of the passengers on board finally escaped disaster and survived.
