As Duas Irenes plot
"One name. One secret."
By chance, Irene discovers that another 13-year-old Irene lives in the same town. She observes the confident, cheerful girl who lives alone with her mother. She is fascinated by this other world beyond the boundaries of her own traditional family. This other Irene seems free. Soon the two girls, who are apparently so different from each other, will spend every day meeting guys at the cinema or going to the lake. When they start talking about their fathers, they find they have more in common than they thought.
