Overview: Simon Reeve continues his epic journey around the world following the Tropic of Cancer, the northern border of the tropics region. Simon rejoins the Tropic of Cancer in Egypt and follows it through Saudi Arabia, Dubai and Oman. In Southern Egypt, next to the ancient temple of Abu Simbal, Simon meets Nubians struggling to maintain their culture following the damming of the Nile and dives in the pristine reefs of the Red Sea. In Saudi Arabia he goes racing with the Jeddah Boyz; and in Dubai he meets construction workers suffering in the economic downturn and he watches as rare baby green giant turtles start their own epic journeys as they head into the Arabian Sea from the beaches of Oman.
