For many years, Florian Ledoux has lived and filmed on the sea ice of Svalbard. One day, a young polar bear crosses his path. He names her Grinch. Orphaned too soon, she grows up alone on the ice. Florian follows her evolution, witnessing a fragile life in the heart of a changing world. Between them, there is no contact, only silence, distance, and presence. Yet a bond slowly forms. Until the day Grinch disappears. Between Breaths revisits this pivotal encounter, a film about memory, loss, and the fragile, invisible ties that bind us to the wild.
