At the start of the school year, Balma experiences significant changes: new classmates in a new high school, her first menstruation, debates with male classmates about women’s work opportunities and the loss of a loved one. Therefore, Balma feels sad and concerned.

But everything changes when Grandma Elisa gives her great-grandfather Daniel's personal diary. That, in addition to a visit from a female aviator, will help Balma to discover a new passion and plan her future.
