The salvage crew aboard the tugboat Arctic Warrior is the best in the business. Under the leadership of their Captain, Sean Murphy, and with the expertise of salvage team leader Maureen Epps, they can locate any abandoned vessel, patch it up until its seaworthy, and drag it back to shore for a price. Canadian Air Force pilot Jack Ferriman recruits the team to investigate a mysterious vessel he has spotted floating adrift off the coast of Alaska in a remote region of the Bering Sea. The team discovers the remains of the fabled Antonia Graza--thought to be lost at sea for more than 40 years. It's a hell of a find--the salvage rights alone could be worth a fortune. And by the law of the sea, any vessel discovered on international waters can be claimed by whomever is fortunate enough to find it--and skilled enough to haul it back to port. But once onboard the eerie, cavernous ship, the crew of the Arctic Warrior discovers that the decaying vessel is anything but deserted. It's home to something more deadly and horrific than anything they've encountered in all their years at sea. Now the crew must uncover the truth about the ship's past and unlock the mystery that threatens their very survival.
