The team has secret intel on a wreck that might be a legendary 1930s disappearance: the champion racing yacht known as Ingomar. Lured by a strange light, the Ingomar's seasoned crew smashes into an unseen obstacle, even though their charts show clear water. The crew escapes in a lifeboat only for the Ingomar to vanish behind them, never to be seen again. Now wreck hunters Mike Barnette and Jimmy Gadomski have found an artifact-rich wreck site that could be the long-lost yacht. Meanwhile, the rest of the team investigates the strange phenomena that lurk in the Graveyard of the Atlantic. What doomed the Ingomar?
