"Diamond Divers" chronicles the dangerous expedition of this enterprising maritime crew as they trek halfway around the world, from Washington State to the infamous Skeleton Coast off the dangerous coast of South Africa, an area renowned for shipwrecks and legendary storms, to mine for diamonds. Meeting them in South Africa are two young, hotshot divers from Houston, TX, who will need to adjust to having to report to Captain John. They will target what is believed to be the original mouth of the Groen River, a coveted spot thought to have an untouched jackpot of diamonds hidden deep in the trenches of the ocean floor. The crew is contracted by the international company Panda Marine, a diamond mining and exploration company specializing in marine mining.
