This is a documentary film about a group of volunteers who risk their lives in the antarctic ocean to protect whales from hunters. Whale hunting has been illegal since 1982 with the only exception being for research purposes. Some fishermen boldly display the words "RESEARCH VESSEL" on their ships so that they may hunt whales illegally. The volunteers feel that they are the last line of defense for the whales because there is no other country or equivalent world force akin to a coast guard that will enforce the international whaling ban.
It's a dangerous game of cat and mouse in the antarctic ocean between the hunters and the hunted and the scenery is absolutely beautiful. If you think that you might interested seeing this, out library has a copy on dvd.
