Amelie is a young Paris waitress who discovers an old box of childhood treasures hidden beneath her apartment floorboards, anonymously returns it to its rightful owner and watches from a distance as his life is transformed by the discovery. Thus begins her odyssey: a series of inventive plans to straighten out other people's lives. Almost as if by magic, Amelie begins to transform the lives of her ordinary neighbors - mostly for the better if they've earned it and occasionally for the worse if they deserve it - but she always hides behind a veil of mystery and anonymity. This works for her until she meets an intriguing young man named Nino. Now the question is: will she have the courage to do for herself what she has done for others?
