Control Voice: (opening narration) In northern Greenland, the mountains stand like a wall along Victoria Channel whose straight course marks the line of the great Baffin Fault. Until recently not even the Eskimos ventured into this arctic waste, but today, as in other lonely places of the world, the land is dominated by those instruments of detection which stand as a grim reminder of man's fear of man. This is Point TABU, a name given this predominately underground base by a young officer who explained that the letters in TABU stood for 'Total Abandonment of Better Understanding'. Some two hundred men and a few women make this their permanent residence. Their task is to maintain a constant alert against enemy attack and be prepared to respond to it devastatingly.
