Diving With a Purpose is a collective of Black scuba divers who search for long-lost slave wrecks. They are on a mission to raise the silent voices of the captive Africans who went down with those vessels and bring them back into our collective memory. We join their youth diving program - YDWP - in Biscayne National Park, Florida Keys, as they head out onto the ocean in search of the Guerrero. The Guerrero was a pirate ship being chased by a British ship HMS Nimble when it ran aground in 1827. It had 561 captive Africans on board, of which 41 drowned.
