Amos Nachoum is one of the world's greatest underwater photographers. Fascinated by the most fearsome creatures on Earth, he has developed a unique approach, that puts him face to face with his subjects, without any protection. He swam with crocodiles and killer whales, with anacondas and with great white sharks but one major predator has always eluded him: the polar bear. He tried before and barely escaped, but now, as he nears the end of his career, he is determined to give it one last shot.
