Many of us take swimming for granted but for some adults it's not as easy. The nine adults seen floundering across a pool designed for six year olds in this film are determined to learn but are under constant and growing pressure from an ever pacing and ever haranguing poolside presence: Linda. Instructor Linda has seen it all before. She knows that most of the women will be terrified of getting their hair and faces wet, the men will be embarrassed by their lack of prowess, and all of them will probably have to conquer demons that run much deeper than a fear of water. And she is going to make absolutely sure they crack it. "This is it - it's now or never!" declares 54-year-old Sandy from Southend-on-Sea. But at the end of the second week, still reluctant to get her face wet and asking for armbands, Sandy reveals stories of a cosseted childhood that still haunt her adult years - the girl who was never allowed to play with other children has become the woman who hides behind an ever present mask of mascara and refuses to remove her contact lenses. But dry faces don't wash with Linda. Until now Mandy has spent thirty years never daring to put on a swimming costume. "Quite petrified", she tells Linda before the first lesson begins. "On a scale of one to ten?", "Eight", she says, but she is as determined to be able to swim a full length as well as any one of them. Kitchen salesman Wyn, meanwhile, has got the patter. "Not scared of the water," he tells Linda. Three weeks on, however, he is pouring out his history of nervous tension to his disappointed teacher.Finally, after 12 lessons and six weeks, Linda leads her proteges to the ultimate test in the big pool. But who will sink, and who will swim?

For most of us, monkeys are mischievous creatures we love to visit at the zoo. But for South African Karin Sachs the animals are more than an exotic pet - they're her life. Baboons are genetically similar to humans and share 91 per cent of our DNA, but in South Africa the animals are seen as pests. In search of food, the primates have begun to encroach on populated areas. Infuriated by their destructive behaviour, farmers often shoot the wild creatures on sight. "Even animal conservationists hate baboons," admits Justin O'Riain, Director of Baboon Research at Cape Town University. But Karin Sachs has devoted ten years of her life to living and working with baboon troops, and has even learned how to talk to them. Obsessed with primates since childhood, Karin now lives with her boyfriend John and 13 vervet monkeys. She has befriended a local Gaia baboon troop and often takes care of abandoned primates found in her local community. The latest arrival to Karin's make-shift animal sanctuary is two-year-old Kajika. But taking in the sick animal brings back painful memories for Karin, who lost a baby baboon in her care when it was attacked and killed by a wild male. Will Karin be able to help the adolescent primate to be accepted by his own kind in the wild? More to the point, after caring for Kajika for months, will she be able to let him go?

Louis Theroux visits Central Valley, California - home to some of the most impoverished rural towns in America, where crystal-meth addiction is among the most prolific in the USA. In Fresno, Louis finds a community ravaged by this cheap and highly addictive drug. It is hard to find anyone whose life hasn't been touched by this drug in one way or another. As he infiltrates the town, Louis comes face to face with meth abuse as addicts invite him into their homes. He becomes surrounded by the madness of daily addiction and the meth-addled confusion which is breaking this society apart. Louis sees its impact through the eyes of the local police force and meets Diane and Karl, a couple who have sustained their marriage, despite 25 years of meth addiction and the loss of the custody of their five children. At residential centre Westcare, Louis sees the work being done to combat the destruction caused by the drug. Run by ex-addicts, the centre offers a six-month rehab programme. Louis sees the extraordinary challenges faced by the centre which deals with a whole range of issues: from old timers, who repeatedly return to rehab programmes; to young meth-addicted families; and babies who are born, hooked, to mothers who are trying to care for them while trying to kick their own habit. At Westcare, Louis meets Senteka, the mother of a teenaged daughter. Senteka is making a last-ditch attempt to kick meth in order to make up for missing her daughter's childhood. As the majority of those attempting to kick their addiction eventually relapse, all Louis can do is hope that Senteka is telling the truth when she swears that she is "clean". Addiction is laid bare as Louis seeks out the stories and the people behind the drug.
