Rozali Lorant is the dreamer owner of a small stationery store in Saint Germain, the heart of Paris. If it were up to her, more and more people around her would be sending cards.

Although cards with the prettiest wishes are her specialty and success, things are not going so well when it comes to fulfilling her own wishes. One day, an elderly gentleman, stumbling into her shop, knocks over the stand with the cards.

Rozali discovers that the man who has clumsily landed in her life is none other than her beloved—and famous—childhood author, Max Marsei. When he proposes that she illustrate his new (and probably last) book, Rozali agrees, and a unique friendship is born between the two eccentric artists.

The wishes of so many years finally begin to come true, until a clumsy American professor barges into her shop, accusing both her and Marsei of plagiarism. Rozali cannot tell if love is knocking on her door or if some big trouble is coming her way.
