The MSC Napoli was badly damaged by storm Kyrill and evacuated in a rescue operation, but left behind; salvaging this ship should become a complicated and expensive affair.

Two rookie salvage masters face a baptism of fire as a Russian freighter gets battered by typhoons in Japan and a stranded ferry in Mexico threatens a holiday playground with environmental disaster.

Blocking a heavily-travelled ocean highway, a sunken freighter slows traffic off the coast of Gibraltar. The New Flame’s engine room – one of her most valuable assets – is miraculously dry, but water is seeping in at an alarming rate. To remove the ship, crews must cut the boat in half. Using special thermal lances, divers take on the exceptionally risky task of cutting cranes on board in preparation. But an approaching storm forces the crew to abandon ship and much of its equipment. Returning to the New Flame, the salvage team finds its equipment gone– the engine room is lost and it is now impossible to refloat the stern. The team must now race to cut up the ship and remove her piece by piece and save 30,000 tons of scrap metal worth millions of U.S. dollars. Off the coast of Japan, the Russian coal freighter Jane refuses to budge – beached throughout typhoon season and rapidly corroding. Divers must now assess whether the Jane is too damaged to refloat.

Off the coast of Oregon, the impossible job: a veteran salver takes on a wreck that has defeated all others. Off Gibraltar, 700 tons of steel need to be lifted out of a shipping lane, testing a team of salver's engineering skills to the limit.

Oil on a sunken tanker threatens an environmental disaster; a salvage team fights to pump her dry using pioneering diving techniques as they battle ship fires and decompression sickness.

The battle for the MSC Napoli, her oil, and thousands of tons of cargo spilling onto British beaches and into the hands of looters. Challenging the toughest experts in the business; blasting, tearing, plunging into battle with the ship that would not die.
