Documentary that investigates the history and archaeological study of a fleet of over 260 British warships at Lake George, New York, deliberately sunk during the French and Indian War (1755-1763). This action by the British protected their vessels over the winter of 1758-1759 from their enemy, the French. Many warships were recovered by British forces in 1759, but dozens were not and remain in Lake George. The documentary follows a group of underwater archaeologists with Bateaux Below, Inc., a not-for-profit organisation, as they study these 18th century warships and answer questions about the mystery of 'The Sunken Fleet of 1758.' The production is a collaborative project between Pepe Productions and Bateaux Below, Inc.
