Adela Ucar kicks off her visit in the capital of Lagos, an anarchic and electric city with a vital nightlife. Next she journeys to Yoruba Land in the southwest, thought to be the site of the Queen of Sheba's tomb. Adela later meets witch doctors in Oyo, travels to the historic walled cities in the north, hunts for bargains in the ancient Kurmi Market, visits the traditional Fulani village of Chafe and encounters a rare mountain gorilla in Nigeria's eastern highlands.

Cuba was one of the first countries in the world to build a railway, starting all the way back in 1837. At the time, Cuba was the world's largest sugar producer, and its early railways were designed not with passengers in mind, but to transport sugarcane to the mills and refined sugar to the ports. In this episode, host Ian Wright goes on an eye-opening and hair-raising train journey across the Caribbean island of Cuba. The communist country's railway network is dilapidated and very unreliable, but it ends up being a fantastically enjoyable trip.
