Marguerite experiences a triple loss: her mother who dies in childbirth, the dog she inherits, and then her nanny, who her father lets go. Alone after these losses, she finds solace in nature at Mont Noir, which shapes her path to becoming a writer.

It is Saturday, a day of rest. A woman wakes up early so that she can give herself a birthday present: some time to write. But whenever an inspirational moment occurs, it is interrupted by domestic situations that claim her attention: the children, laundry, the meals. The mental load of those tasks ends up being unbearable and she reaches a breaking point.
