Getting out of jail, Grahams resolve and sanity are tested by a month-long search for a boat that can take him back to the African mainland. When hes finally rescued by a European sailor, he hits West Africa in top gear – but can he keep up a punishing schedule when faced with decrepit transport, washed out roads and the rainy season fast approaching?
