During a documentary residency in the Sierra Maestra, Cuba, a filmmaker befriends Sara, a seven-year-old girl who moves between San Pablo de Yao and La Nave. Together, they play and explore a world where Sara is simply a child; within this everyday intimacy, traces of the island’s crisis quietly emerge. The filmmaker transforms this bond into a letter to Sara—a return to those shared days, and a way to think of her from afar after they part.
