The Atlantic Ocean occupies an “S” shaped basin extending between Africa and Europe, and the Americas. In the last 10 years the North Atlantic has claimed the lives of 165 of America’s fishermen, making it America’s deadliest sea. Storms here form too fast to predict, and in the shallow fishing grounds off the east coast, breaking waves can sink a boat without a trace. Despite the dangers, Captain Eddie Welch, a survivor of three hurricanes and a boat sinking, heads out on the Westport. Scallop dredging in the Atlantic is dangerous even for a veteran sea captain, and leaving from the same port is rookie captain Tim Quinn who is out to prove he can handle the Atlantic in winter and bring in $350,000 worth of scallops in just 8 days of fishing.
