Simon Reeve starts his epic journey around the world following the Tropic of Cancer, the northern border of the tropics region.

In this first episode Simon travels from the beautiful Pacific coast of Mexico, where he visits the luxurious holiday resorts of Baja California, before crossing the country's rugged interior.

Along the way he goes on patrol with a heavily armed police unit in Culiacan, headquarters of the fearsome Sinaloa drug cartel, and gets more than he bargained for from a female Lucha Libre wrestler.

The Tropic of Cancer skirts Havana, where Simon learns how allotments are helping the Cubans counter the effects of the US trade embargo; and in the Bahamas he discovers the hidden menace on the beautiful coral reefs that make these islands famous. Show less
