The 50th birthday is usually considered an anniversary to be lavishly celebrated with friends and family – and that was exactly the way Giulia had planned her birthday to be: the place at the restaurant is booked, her closest friends have dressed up for the occasion – only the birthday girl does not show up! The reason is simple: Just when she turns 50 years old, beautiful Giulia finds out that she has become completely invisible to the people surrounding her. Thus, she has completely lost her mood for partying. Aimlessly, she wanders around the city and meets an attractive man whom she takes to a tête-à-tête in bar without any hesitation. Meanwhile, the guests at her party take to alcoholic drinks and appreciably lose themselves in philosophical debates about the sense of life. Simultaneously to this plot line, the film episodically tells the story of an 80-year old woman who does not behave according to her age at all, and about two teenagers who would like to be older.
