The summer of 1975 promised excitement and adventure for twin brothers and college students Mike and Mark, working aboard the greatest ship on the Great Lakes-the Edmund Fitzgerald. She was a 729-foot-long behemoth that had been carrying freight the lakes for nearly 20 years; the twins were seeking first-hand knowledge and experience for their chosen field of engineering. But when the November gales blow, it means deadly danger to any ship on the Great Lakes. As fate would have it, the twins are separated for the November 10th trip... the final voyage of the Edmund Fitzgerald.
