Dzerzhinsk, a Russian city 240 miles east of Moscow, is considered the most chemically polluted town on Earth. Factories producing industrial chemicals (and in Soviet times, chemical weapons) employ a quarter of the 300,000 residents in a city where life expectancy has fallen to 42-47 years, the death rate is 2.6 times higher than the birth rate, and the men are close to impotence. Reporter Tim Samuels recorded a series of in-depth interviews with the inhabitants of Dzerzhinsk for the Correspondent strand, revealing what life is like for the beleaguered populace.

The Yasuni Park in Ecuador is a haven of biodiversity and home to indigenous tribes. It also holds a third of the country's oil reserves. Ecuador had agreed to keep the oil in the ground. But as powerful new interest groups emerge, the future of the Park, and the people who have called it home for thousands of years, come into question.

An estimated half a million women are being transported to Western Europe by sex traffickers every year. It's a multi-million pound business where, for the traffickers, the rewards are high and the risks are low. But, for the girls, the consequences are brutal and potentially dangerous. Following a route which begins in the former Soviet Republic of Latvia and leads to Denmark, Ireland and the UK, Sue Lloyd-Roberts uncovers a murky, cruel world in which employment agencies seduce young women with false promises, unscrupulous pimps abuse them and the police and judiciary turn a blind eye to this contemporary form of slavery.

On September 1, 2004, a group of heavily armed rebel extremists stormed into School No. 1 in Beslan, Russia. For three days, more than a thousand children and adults were held hostage in a sweltering gymnasium, denied food and water, and forced to keep their hands over their heads. The harrowing siege ended on September 3 with a series of explosions and a hail of gunfire that killed some 350 people - half of them children. In this film, the youngest survivors of Beslan tell their story.
