Overview:

The giant squid is a creature of legend and myth which, even in the 21st century, has never been seen alive. But now, an international team of scientists thinks it has finally found its lair, 1,000 metres down, off the coast of Japan. This is the culmination of decades of research. The team deploys underwater robots and state-of-the-art submersible vessels for a world first - to find and film the impossible.
