63-year-old Dolores—a teacher, a wife and mother—has always lived up to expectations. Her life in Barcelona is stable but suffocating: a dull marriage, a grown son about to make her a grandmother, and yet another Christmas far from her hometown. On Christmas Eve, something snaps. After feeling provoked, she assaults a man in public — an impulsive, violent act that seems completely out of character. Suddenly she’s thrust into a hostile system that puts her sanity and womanhood on trial. The world says she’s lost control, but something deeper has been set in motion.
