Six people from around the world are tailing Shell's Arctic oil rig across the Pacific on board the Greenpeace ship Esperanza. As ambassadors of a movement of millions, the six men and women want to expose Shell's reckless plans to drill in the remote Chukchi Sea in the Alaskan Arctic. The Esperanza has been tracking Shell's monstrous oil rig the Polar Pioneer since it left Brunei Bay in Malaysia.
