Bill, Gary and Ruby follow the Pirate Coast of Mexico, heading for a pirate lighthouse which was used for wrecking ships and previously only accessible by boat. The coast is rich in history, from battles to buried gold, but the duo’s greatest foe is the terrain – fast flowing and deep river estuaries and quicksand beaches as well as impenetrable mangroves and 150-metre high jungle clad cliffs. Gary must risk everything to keep an anchor buried to pull Ruby from the ocean’s waves. Before they reach their destination, they must avoid being pulled into the Atlantic ocean by a breathtaking headland crossing to reach the beach that houses the legendary rock.
