Set in a rural Catalan village during the Spanish Civil War, Un jove escriptor tells the story of a summer romance between two young people and reflects on the importance of art through writing. Bernat, a young writer, spends his days observing the people around him and writing in his notebook. One day, he meets Aliena, a girl who hates writing. Little by little, he shows her the beauty of writing, and together they experience an intense summer where a love as passionate as it is fleeting blossoms.
