For almost a century and a half, Her Majesty's Ship Breadalbane lay wrecked and forgotten under the Arctic ice. In the spring of 1983, noted undersea explorer Dr. Joseph MacInnis led a team of twenty men on one of the most difficult, dangerous and unforgettable undersea adventures of the century--to put a diver on board the sunken vessel and recover some artifacts. This film, introduced by H.R.H. Prince Charles, provides a stunning visual account of this historic expedition.
