During the late 19th and early 20th centuries, thousands of Jewish girls fled pogroms and poverty in Eastern Europe for the promise of marriage and a fresh start in South America. Instead, they found themselves sold into prostitution by the Zwi Migdal, a Jewish criminal syndicate that controlled 2,000 Argentine brothels at its peak in the 1920s. Join the Jewish Genealogy Society of Los Angeles for a discussion on, “From Shtetl to Tango: The Untold Story of South America’s Jewish Sex Slavery,” and for a screening of “Passages,” director Gabriela Böhm’s award-winning documentary about unlocking myths and secrets while exploring her family legacy in Eastern Europe, Israel and South America. Sun. 1:30 p.m. $5 (general), free (JGSLA members). University Synagogue, 11960 W. Sunset Blvd., Los Angeles. jgsla.org.
