The red band trailer for 3Some (Castillos de cartón).
María José is studying painting at the School of Fine Arts in a big city. One morning, as she’s preparing a canvas for class, Jaime, one of her classmates, draws her portrait though she doesn't notice. Beside him, admiring his drawing abilities is Marcos, the most talented student in the class. María José expects Jaime to give her the portrait but after he shows it to her, he unexpectedly keeps it for himself. From then on, María José, Jaime and Marcos will share their passion for painting and something more, a love story that will last until their lives as students come to an end and they must face the real World.
