El castigo

Sandra is late for class. And she is not the first time, but she is a good teacher, no one at her high school in the Barcelona neighborhood of Sant Andreu can deny it. She has been dating Albert for two years, a writer who, in turn, was her professor at the university, although she sometimes doubts how she truly feels about him. Between one class and another, during the coffee break in the middle of the morning, Sandra begins to notice a newcomer to high school, a young man named Minu. Sandra is also tutoring a student, Izan, who is about to get into trouble and will soon need his help. But she has had a turbulent relationship with her sister and her mother since childhood, and, although no one knows it, she has been at war with herself for a long time. To try to straighten the course, Sandra will evoke the girl that she was, before it is too late.
