Travelling forward in time to 30,000 years ago, it's the middle of an ice age. The landscape is dominated by mighty mammoths, living side-by-side with woolly rhinos, giant deer and two separate species of human. The programme follows the fate of a herd of mammoths in their annual struggle against the harsh ice-age conditions. Every summer they spend on the grassy plains of what will one day become the bottom of the North Sea, but every winter they are forced to head for the less exposed valleys further south. It is a journey fraught with danger: mammoths can get trapped in frozen bogs, and the herd must run the gauntlet of hunters like cave lions and the deadly Neanderthals.

Without us noticing, modern life has been taken over. Algorithms run everything from search engines on the internet to satnavs and credit card data security - they even help us travel the world, find love and save lives. Professor Marcus du Sautoy demystifies the hidden world of algorithms. By showing us some of the algorithms most essential to our lives, he reveals where these 2,000-year-old problem solvers came from, how they work, what they have achieved and how they are now so advanced they can even programme themselves.

On a dusty highway between Australia's most isolated city and its largest gold pit lies Coolgardie - where the arrival every three months of a new pair of foreign backpackers to work the only bar in town is a keenly anticipated event. Fresh off the plane and lured by the promise of an authentic outback experience, Finnish travellers Lina and Steph find themselves en route to a dot on the map - to pour beers, replenish depleted travel funds, and live amongst the locals. But their working holiday quickly deteriorates into a baptism of fire.
Harangued by their new boss, relentlessly pursued by booze-addled patrons, and prey to the madness and malaise of an environment as claustrophobic as it is isolated - the girls soon realise that to meet expectations out here, they'll need to do more than just serve drinks.
