Gertrúd is a middle-aged music teacher, weary of family life with her art-restorer husband and their teenage son. Her world is turned upside down when a former student of hers, the beautiful Albán, suddenly shows up. Albán is a woman, but that's not the only problem with her. Her presence prompts questions about the past, present, and future. Reality, memories and dreams intermingle, and the old family roles slowly begin to change.
