In 1937 the German ocean liner St. Louis set sail from Hamburg to Cuba. Aboard were nearly 1,000 Jews hoping to escape the Nazis. But midway across the Atlantic their visas were revoked. First Cuba, then the United States and Canada, refused to take the refugees, who were returned to Europe.

Scott Miller of the United States Holocaust Memorial Museum reveals the varied fates of the 937 refugees aboard the St. Louis, following the clues through archives in Havana, Europe, Israel, and the U.S., and through New York City neighborhoods to track down leads provided by friends, family members, and others who knew these passengers.
