Das gefährliche Alter (1927)

The gorgeous 40-year-old Elsie Lindtner lives in a beautiful house, and is married to a respectable university professor. And yet, there’s something that nags her. She’s about to reach “the dangerous age”, when beauty begins to fade and boredom kicks in. She falls in love with a younger man and divorces her husband, but ends up hiding away in a country house where she can age in secret. (Stumfilm.dk)
