Eva, 12 years old, is looking forward to spending the summer in Senegal, her parents' country of origin, where she has never been. But when she arrived, her enthusiasm gave way to disappointment. She had come looking for adventure but she gets bored. She doesn't know anyone and feels like a stranger. Moreover everyone here calls her Binta, it is not even her name! The only one who is able to captivate her is her grandfather, Abu, who tells her old legends of the country. But he gets very sick.
