In the summer of 2014, an extraordinary event took place deep beneath the freezing waters of the Canadian Arctic. A team of underwater archaeologists and historians embarked on a daring expedition in search of the lost and legendary HMS Erebus, a British naval ship that mysteriously vanished during Sir John Franklin's ill-fated 1845 expedition to find the Northwest Passage. This remote and treacherous region, known for its relentless cold and treacherous ice conditions, held the secrets of a maritime tragedy that had puzzled explorers and historians for over a century and a half. Equipped with advanced technology and fueled by the passion for uncovering the past, this determined team was about to make a discovery that would rewrite history.
