20th October 1944: US troops storm ashore on the island of Leyte. After two long years under Japanese occupation, the Liberation of the Philippines has begun.

The invasion triggers the Japanese Navy's last-ditch attempt to stop the American advance in the Pacific. The result is the largest naval battle in world history.

This film offers an extraordinary new insight into this important battle in the Pacific War. Aerial photographs have been brought to life using the latest computer imaging technology to create a 3-D model of the Philippines. Now it is possible to follow both the American and Japanese fleets as they battle for supremacy in the waters around Leyte Gulf.
