Louis Theroux

Another chance to see the BAFTA award winning presenter travelling to northern California to visit America's notorious San Quentin State Prison.

Built in 1852, San Quentin is one of America's oldest prisons and suffers from chronic overcrowding. Although famous for its death row the prison's main task is to house a transient population of 3,000 murderers, sexual predators and small-time criminals.

Louis spends two weeks with these inmates and quickly discovers that they inhabit a strange world within a world with its own rules and its own brutal code of conduct.

He meets amongst others David Silva who is serving 521 years and 11 life sentences and is locked down for 23 hours a day. Silva's crimes as he describes them 'would never be forgotten' and he talks of how he faces up to the prospect of never leaving prison.

Louis meets Deborah and Rob a transgender couple who live like husband and wife and how Deborah feels that after 20 years of continual offending, San Quentin now feels like home.

Louis travels to Limpopo Province to stay in a hunting lodge. Hunting in South Africa has become easier than ever before - in fact, it is a blossoming tourist industry. The cost of a trophy animal ranges from as little as $250 for a baboon to as much as $70,000 for a rhino. The animals are bred to purpose on private game farms. In fact, lion breeder Piet insists that hunting, by putting an economic value to the animal, has allowed populations of exotic species to flourish.

Louis Theroux joins the Philadelphia Police Department patrolling the most dangerous part of one of the most violent cities in America.

With gun carrying drug dealers on every corner, it is now normal for the centre of Philadelphia to stage 30 or 40 homicides a month. Embedded within the Philly rapid response teams, Louis feels a palpable sense of adrenalin mixed with frustration as police and the drug dealing 'corner boys' take each other on night after night. Here is a community desperate for protection but unwilling to talk to the law enforcers for fear of street retribution.

Louis senses a society trying to contain a lawlessness born out of poverty and disaffection. There's mistrust on all sides, although over time Louis sees a complex picture evolve - there are cops and robbers, guns and violence, but also an understanding between both sides. They are all part of 'The Game' which plays itself out night after night between the community and the cops given the task of policing it.

Louis Theroux travels to Johannesburg, where the residents find themselves increasingly besieged by crime. Despairing of the capability of the police and the courts to protect them, many have turned to an industry of private security, offering protection for a price. Are the sometimes brutal methods of these private police really a solution or just another part of the problem?

The first stop for Louis is a meeting with William Mayangoni, the local co-ordinator for a security firm known as Mapogo. Based on the outskirts of Diepsloot, one of the squatter camps that ring Johannesburg, William investigates thefts for his mainly white clients. When he catches a suspect, he gives them 'medicine': the alleged offender is beaten with a leather whip known as a sjambok.

Although his clients seem to support what they see as 'an African solution to an African problem', William's methods alienate the people of Diepsloot. Finally, their patience snaps dramatically, and William has to call out the real police in order to protect himself from the vicious threat of the mob.

In the centre of Johannesburg, a security company called Bad Boyz work in an area called Hillbrow, notorious for its high crime rate. Louis meets company director Hendrik De Klerk who explains that much of their activity involves reclaiming and securing buildings that have been taken over, or hijacked, by criminal gangs who illegally take rent from tenants. Louis watches dramatic evictions unfold, in which the police and security companies are not afraid to use force to kick out the protesting residents.
