Living in Paris with her partner, the workaholic Mr Frog, and their adorable toddler, Tadpole, Catherine decides to alleviate the boredom of her metro-boulot-dodo routine by starting a blog under the name of Petite Anglaise.

Writing with disarming honesty about Paris life, about the confines of her hollow relationship with Mr Frog and about the wonder and pain that comes with being a mother, she finds a new purpose to her day.

As Petite Anglaise, Catherine regains her confidence and makes virtual friends, including one charismatic and single Englishman who lives in Brittany, James. And after meeting James one evening in a bar, Catherine feels she has regained her ability to fall in love, too.
