Jorgelina and Luciana are sisters. As Luciana enters puberty, she begins to grow apart from her adoring younger sibling. Rather than tag along with Luciana at the beach, Jorgelina decides to spend the summer with her father in the country. There she develops a friendship with Mario, a farm boy. As the children explore the Pampas prairies, they begin to question the similarities they share, and what makes them different. This is a tender portrayal of the unexpected revelations that affect two children as they begin the bumpy transition to adolescence.
