The underwater photographer Amos Nachoum’s white whale is not a whale at all, but is, instead, a polar bear. Nachoum has swum with crocodiles and killer whales, with anacondas and with great white sharks. But one major predator has always eluded him. The legendary stills photographer has always dreamed of swimming underwater with a polar bear and capturing it face-to-face on film. He tried before and barely escaped with his life, but now, at 65, he is determined to give it one last try. No one has ever shot polar bears the way Nachoum wants to — while swimming with them — and for good reason: polar bears consider humans part of their diet. Determined to get the shot this time, the photographer embarks on a five-day Canadian Arctic expedition with a small crew. The Old Man and the Sea, Hollywood style.
