Oh, diese Jugend.

Engineer Franz Bach seems to have gone astray once again. Working overtime, nagging at his wife and his parents sleeping apart lead the children to come to this conclusion. It can't go on like this. His youngest son Täve does his best to keep his father away from the very young intern Irene. Täve's 19-year-old brother, on the other hand, tries to steal his father's mistress. His wife Margarete also wants to bring a breath of fresh air into the marriage.
