A small island in northeastern Italy in the winter of 1900. Young Agata’s baby is stillborn. In the Catholic tradition, an infant that has not taken its first breath cannot be baptized, and its soul is condemned to Limbo without a name and without peace. But Agata has heard about a place in the mountains up north where infants can be brought back to life for that single breath necessary to allow baptism. So, Agata leaves the island in secret, her daughter’s body hidden in a box, and undertakes a dangerous voyage with nothing but hope to guide her. She doesn’t know the way and she has never seen snow in her life. She meets Lynx, a wild, solitary boy who knows the territory and offers to help her in exchange for the mysterious contents of the box. Despite their mutual distrust, the pair set off on an adventure during which their courage and friendship will enable them both to come close to a miracle that seems impossible.
