Madrid, early twentieth century. Julieta and Alberto are a couple who have been married for several years, but who are still as much in love as the first day. He is the half-orange she always wanted, and their bond of union is growing stronger. One day, Alberto, in the fear of losing her, decides to start writing to his beloved several letters of love under the pseudonym of 'Count of Rocambole'.
