In this feel-great charmer, the ever-gorgeous Sophie Marceau stars as Margaret, a high-powered business woman who manages her career with steely determination. But on her 40th birthday, a provincial solicitor sends her a package of old, forgotten letters she wrote to herself when she was seven, what the French refer to as “the age of reason”. Re-reading them one by one, Margaret plunges back into the hidden memories of that hopeful young girl… but they cast doubt on all her certainties and make her revisit her life choices. Margaret realises that she has become the opposite of what she hoped as a child. Is it too late for her to make a change?
