Finding the Blue follows Professor Gianni Pes in Arzachena, Northern Sardinia, where for several years he has been conducting research that could lead to the identification of a new Blue Zone. Pes delves into archival documents, parish records, and stories of centenarian families, engaging with local residents and scholars. The film weaves together science and memory, portraying a land that has undergone radical transformations with the rise of the Costa Smeralda yet still preserves a surprising root of longevity. An investigation that combines the strength of data with the power of lived lives.
