The White Ribbon (2009)

In a village in Protestant northern Germany, on the eve of World War I, the children of a church and school run by the village schoolteacher and their families experience a series of bizarre incidents that inexplicably assume the characteristics of a punishment ritual. Who could be responsible for such bizarre transgressions? Leonie Benesch, Josef Bierbichler, and Rainer Bock star in director Michael Haneke's Palm d'Or-winning period drama. - Jason Buchanan, All Movie Guide
