Kristin Miller is 70 years old. It is his birthday. She is an eminent art historian. When she was young, she was a passionaria who was in all the fights, who climbed onto the Parisian barricades of May 68 with the students of her generation. Later, she followed her vocation by settling in Florence, with her young children, to do her research on the painter Giotto. Her birthday should be a time for celebration, but when her two sons reveal their version of the past, Kristin must face the consequences of her commitment.

Apologia takes a look at the ideals of the baby boomers, these young people who arrived in their millions in an exceptional parenthesis in History and who dreamed of changing the world with love and peace. All you need is love , Give peace a chance were the mottos. But of these values, of these fights, what remains? Apologia is also an observation on what certain women have had to sacrifice to pursue their careers and pursue their dreams.
