After finding the bow of the Eagle 56 at the bottom of the Atlantic, explorers search for the rest of the warship to uncover why it sank.
After four years and countless dead ends, a team of civilian investigators has found pieces of the sunken Eagle 56, the Holy Grail of New England shipwrecks. They want to reveal their discoveries to both the Navy and the families of the warship's crew, but their case is not yet complete. They still need the last and most important piece of the wreckage: the ship's boilers. With winter quickly approaching, time is running out to find the final clue, solve the 75-year-old case, and honor the sailors who died in the disaster.
