Chuchelo plot
When 12-year-old Lena moves to a new city with her grandfather, they are both excluded because they are too different. He is a fickle eccentric collector of old paintings and she is too shy and anxious to make real friends. When she's accused of something she didn't do, the other kids decide to go after her. At that point, the whole thing escalates. Lena begins to feel a determination to resist her harassers, but she's still waiting for the right help from one quarter or another to strike.
