A comedy about aging youth and other eternal truths. Of all days precisely on her fiftieth birthday Julia has to experience that age makes you invisible. Frustrated she goes shopping and makes an acquaintance spontaneously deciding to spend the evening with this stranger rather than with the guests of her own birthday party. They wait for her in a restaurant all dressed up and groomed lively debating the years that have passed. The truths and wisdom of Julia's closest friends on aging and growing old are drowned increasingly in sufficient quantities of alcohol. In the mean time on her eightieth birthday Leonie sulking over the loss of youth is rebelling against her daughter the senior citizen's home conventions and old age in general - and joyfully sabotaging the party in her honor.
