Recorded in Paris, Theatre de l'espace Cardin. Louise is single, Alexandre is in the middle of a divorce, she has no children, he has three, she is more on the left, he is more on the right. Both are over fifty! If there is no age to fall in love ... love and life together are an equation that gets complicated with age! The charm of chance encounters is that they bring together people who attract each other without necessarily being compatible.
