Banketten (1948)

Jacob Cotten is a rich banker quickly approaching his 60th birthday. He is concerned that neither of his sons are willing or able to be in charge of the bank. One is a spoiled parasite unable to do an honest day's work; the other has devoted his life to the communist youth club. Meanwhile, his beloved daughter Vica is unable to divorce her masochistic husband and gets herself a lover, an idealistic young medical student.
