What happens when a community rooted in cornfields and Christianity is suddenly transformed into a place presumed to have more rabbis per capita than anywhere else in the world? How does a tiny Iowa town respond when hundreds of Mexican immigrants hit the heartland in search of the American dream? What happens to community cohesion when Hasidic Jews, people whose religion guides them to steer clear of swine, move to a place where the greased pig contest is one of the biggest shows around? How does a once homogenous population react when the promise of the American melting pot seems to go unfulfulled? And what really happens when multiculturalism moves to the most unlikely of places? 'Postville: When Cultures Collide' is an hour-long documentary that explores the struggles and rewards, the complexity and comedy of instant multiculturalism. The documentary tells the story of Postville, Iowa, a town that, for nearly 150 years, was all white, all Christian and all but removed from melting pot America. Seemingly overnight, this farming town of 1500 found itself home to nearly 300 Hasidic Jews, 400 Mexicans and dozens os Eastern Europeans. Through the prism of Postville, the documentary examines the challenges of American multiculturalism, investigating the meaning of community, ponders what the American dream has come to mean today and questions just whose dream is going to shape the future.
