It's one of those nights in Las Vegas: there's been a night club shooting; a dead stripper is found in a blood-soaked hotel room; ET is found buried in a dry lake bed; a transient commits suicide by electrocution, and as usual, nothing is as it seems.

Added to the multiple crime scenes, an introspective Sara is back from a much-needed vacation after her near-arrest for driving under the influence of alcohol, and a nervous Greg is handing over the DNA lab to his potential replacement (guest star Reiko Aylesworth) as he begins his move out into the field, under the watchful eye of Grissom.

Catherine takes the call at the Palermo Hotel and cannot figure out how the customer found with the dead stripper could have fallen asleep at such a gruesome and violent crime scene. He's claiming innocence by amnesia, and he may be telling the truth. Catherine finds a blood sample that IDs a bouncer at the strip club where the dead woman worked.

Untamed North America: The Time of the Wolves

ATV World

Abisi, his jaw still hurting from his run-in with a porcupine, prowls on the snow-covered plain. Following a mad chase, a prairie dog becomes the chosen meal.

A slight rise in temperature has lured the brown bear from his deep sleep, and from his den. He ventures outside. Could spring already have arrived? He conducts a quick check and retreats, slipping back into his winter torpor.

Sox, the female cougar, carefully conceals what remains of the doe carcass she has been feasting on. But Wamitt and Inap, the pair of wolves, have detected the remnants.

Wamitt, the male, will eat first, while his mate awaits her turn impatiently. The end of winter is also witness to the wanderings of a young moose elk. Emaciated and ravaged by vermin, there's little hope that he will see the arrival of spring.

Pilot Guides: London 2

ATV World

It takes two to capture the huge and exhilarating city of London, so Jonathan Atherton and Megan McCormick share the billing as they try to encompass all that Britain's capital has to offer.

Megan kicks off at the biggest Ferris wheel in the world, The London Eye, while just five minutes' walk away Jonathan has the first of two encounters with the Queen at the royal pageantry of the Trooping of the Colour. But they soon head off in different directions. Jonathan explores the colourful East End markets and the drama of the British museum. Megan finds new architecture in The City. Jonathan discovers a stunning marble Hindu temple in the suburbia of Neasdon and Megan tries out her Shakespeare at the Globe theatre.

From the markets of Camden to Speakers' Corner in Hyde Park, the London City Guide 2 offers endless surprises that express the diversity of one of the world's most exciting cities.

Supervolcano

TVB Pearl

The last super-volcanic eruption occurred 74,000 years ago. It plunged the world into darkness for six years, tipped us into the last Ice Age and reduced the human population to only 2,000.

The presence of the supervolcano beneath Yellowstone Park is not disputed. Its hot springs, geysers and bubbling mud pools are all outward manifestations of the presence of a huge body of magma which resides not far beneath the Earth. Scientists know that one day this molten lava bulging against the Earth's crust will burst through. It's just a question of when.

When Yellowstone erupts, one billion people will die. The US will be obliterated and the world thrust into a volcanic winter that could persist for decades. It is virtually impossible to predict when this will take place. Yet that is the responsibility of the scientists monitoring Yellowstone. Aware of the risk of mass panic - no one wants to make a false call.

The Triplets

ATV World

Antoni Gaudi was not only one of the most dazzling and playful geniuses in the history of architecture, but also a solitary and mysterious person. Or at least he was until, one fine day, he received a very special visit. Well, three visits: from Anna, Teresa and Helena, the triplets!

The story begins in New York, where Gaudi has drawn up plans for a magnificent banana-shaped skyscraper. But the project is cancelled and he returns home to his country feeling frustrated, old and finished, not to mention pursued by a band of ghost warriors. In Barcelona, Gaudi is given another chance: to build La Pedrera. And this time, he'll make no mistakes. He'll be an architect free of all eccentric ideas! He must return to the straight and narrow! No more curves!

Cirque du Soleil: Solstrom - Cosmic Wind

ATV World

A discotheque occupies an entire planet situated somewhere in intergalactic space.

As is the case for all Saturday night hot spots, entry into the disco can be difficult. A customs officer hand-picks the clientele very selectively. For one inoffensive wise guy in particular, admission is very difficult.

The discotheque attracts an odd clientele - extraterrestrials, creatures of the sun, an intergalactic adventurer named Milla Jovovich, Conrad MacLeod from the film Highlander (played by Christopher Lambert), and Deepak Chopra, guru of the stars. It seems to be similar to a discotheque on Earth, but in appearance only.

When extraterrestrials party, their lovers' quarrels are more shocking, feats are more flamboyant, beautiful women are different and getaways are clearly more spectacular!
