The heartbreaking and ultimately hopeful story of an abandoned polar bear cub named Nora and the humans working tirelessly to save her and her species, whose uncertain future in the accelerating climate crisis is closely tied to our own.

Six days after giving birth, a polar bear named Aurora got up and left her den at the Columbus Zoo, leaving her tiny, squealing cub to fend for herself. Hours later, Aurora still hadn't returned. The cub was furless and blind, and with her temperature dropping dangerously, the zookeepers entrusted with her care felt they had no choice: They would have to raise one of the most dangerous predators in the world themselves, by hand. Over the next few weeks, a group of veterinarians and zookeepers would work around the clock to save the cub, whom they called Nora.
