A sudden ocean swell overturned the tugboat Jascon-4, plunging Harrison and his crew into the depths of the Atlantic Ocean.
Trapped in an officer's cabin, with an air pocket shrinking, Harrison faced nature's unpredictable power head-on.
In the pitch-black ocean, with no food or water, Harrison stacked mattresses to stay afloat, battling the cold and fear of drowning.
After 60 hours, rescuers, expecting to recover bodies, found Harrison alive in a vanishing air pocket. A miraculous survival against all odds.
