The wreck of the SS Georgiana, valued at over $50,000,000 and said to have been the most powerful Confederate cruiser, is discovered by teenage diver and pioneer underwater archaeologist E. Lee Spence, exactly 102 years after its destruction.

The Georgiana was a brig-rigged, iron hulled, propeller steamer belonging to the Confederate States Navy during the American Civil War. Reputedly intended to become the "most powerful" cruiser in the Confederate fleet once her guns were mounted, she was never used in battle. On her maiden voyage from Scotland, where she was built, she encountered Union Navy ships engaged in a blockade of Charleston, South Carolina, and was heavily damaged before being scuttled by her captain. The wreck was discovered in 1965 and lies in the shallow waters of Charleston's harbor.

The Confederate States of America (CSA), also known as the Confederate States (C.S.), the Confederacy, or the South, was an unrecognized breakaway republic in the Southern United States from 1861 to 1865. It comprised eleven U.S. states that declared secession: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. These states fought against the United States during the American Civil War.

A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial.

Underwater archaeology is archaeology practiced underwater. As with all other branches of archaeology, it evolved from its roots in pre-history and in the classical era to include sites from the historical and industrial eras.
