On March 25, 1942, nearly a thousand young, unmarried Jewish women boarded a train in Poprad, Slovakia. Filled with a sense of adventure and national pride, they left their parents' homes wearing their best clothes and confidently waving good-bye. Believing they were going to work in a factory for a few months, they were eager to report for government service.

Of those 999 innocent deportees, only a few would survive.
