Each year, about nine hundred whales are brutally killed by Japanese hunters in the waters of the Antarctic. The whale meat is to be served in Japan’s sushi restaurants. Thirty-seven men and women decide set out on the Greenpeace ship Esperanza in order to pursue the Japanese whaling fleet and create a human barrier between the whales and the Japanese harpoons. The film not only recounts this spectacular adventure, but also portrays the personal stories of the international crew, their daily lives on-board, their problems, their fear of failure and their homesickness.
