Albert Korn, a successful retired tire executive, sets sail to Bermuda onboard the Mystic Lady, his new 35-foot sailing yacht. The relatively short trip from Nassau is uneventful until the cruiser hits a floating piece of debris that penetrates the hull of the luxurious yacht.

Having to abandon ship, the 55-year old mariner is marooned at sea just 25 miles from land. The adventure heats up as the sun beats down on the castaway adrift in the Gulf Stream. With nothing but a life vest and a small pocketknife to survive, the drifter is carried into a turbulent current that proves to be the beginning of a strange adventure into time.
