Frantz is set in Quedlinburg, Germany, in 1919, just after the Great War (World War I) has concluded, though the aftermath is still quite fresh in the hearts and minds of the people. A local woman named Anna is but one of many who are mourning for the loss of young men in the war, grieving her beloved Frantz, killed in battle before he would return and marry her as planned. Living under the roof of Frantz's parents, Dr. Hans Hoffmeister and his wife Magda, Anna regularly places flowers on Frantz's vacant grave-site, only to discover a mystery man has already come to do the same.
