In 1930s Budapest, naïve orphan Luisa Ginglebuscher becomes an usherette at the local movie house, determined to succeed in her first job by doing good deeds for others and maintaining her purity. Luisa's well-meaning lies get her caught between a lecherous businessman, Konrad, and a decent but confused doctor, Max Sporum. When Luisa convinces Konrad that she's married to Max, Konrad tries everything he can to get rid of the baffled doctor.
