This is about a organisation Dwp diving with a purpose who have traced some shipwrecks that they believe may be connected to slave ships that sank, they found objects that say they were used in slavery, they then get upset about a spoon and ivory. They risk their lives diving for these objects but the laws prevent them from recovering bigger objects. The slave trade was brutal and story should be told, but the first and second program are slow and dragged out. The series does get better and the story does show that even black people were involved at point of sale, but as slavery was accepted at the time people who were slaves and educated Americans rose up and help free slaves before the civil war. If you stick with the program it does have some merit, but just not all about begin of slavery, but more about ships and how slaves were packed and died on shipwrecks. The stories in episode three of people escaping slavery and finding freedom was more interesting than story of a shipwrecks.
