The third of six films
Narrated by Kenneth Allsop

From the shores of the Caribbean in Venezuela up through the dripping cloud forest to the bleak moorlands and peaks of the Andes, across the world to Mount Kenya with its weird giant plants and tiny sunbirds... This vertical journey takes us from the equivalent of the tropics to the poles; to regions where plants and animals somehow survive in the most extreme conditions. There is even a plant that makes its own anti-freeze and there are lobelias and groundsels as tall as trees.

The third episode of this four-part series focuses on Brazil and the strange ceremonies the people use to call on the spirits, both good and bad, to help them with their daily problems.

Today they fulfil a need for the very poor living in the shadow of the very rich.

In central Europe two million combat troops have faced each other for 23 years, mutually suspicious, ready for war. They are the forces of the rival military alliances of NATO and the Warsaw Pact, and they represent the highest concentration of armed force anywhere in the world.

Scared at the prospect of nuclear war, the two sides are attempting to reduce their forces. But reduction must be mutual and balanced. As a background to the current political talks. Horizon examines the doctrines and military strategies of the two alliances and shows how difficult it will be for the two sides to reach agreement. But if they don't, what then?
