In the unforgiving waters of the North Atlantic, engineers undertake the monumental task of constructing the Hibernia GBS, a massive oil platform designed to withstand the extreme conditions of the Grand Banks. As they build this technological marvel, the project is haunted by the memory of the Ocean Ranger, a tragic disaster that claimed the lives of 84 oil workers. This film explores the immense challenges of building a structure capable of surviving 100-foot waves and collisions with massive icebergs, while highlighting the rigorous safety training that every worker must undergo to survive in one of the world's most dangerous environments.
