Shark Week

an up-too-close-and-personal encounter between underwater photographer Valerie De La Valdene and a nasty school of the predators. "Primal Scream" explores the nature of sharks and of human fear using De La Valdene's footage, interviews with experts and a trip to the Galapagos waters, the site of De La Valdene's near-death experience. In addition to De La Valdene's underwater chiller, "Primal Scream" - the first of the seven all-new Shark Week installments - also previews the upcoming big-screen thriller "Open Water".

The story begins in 1991 with a horrifying shark attack in Hawaii that claimed the life of a local woman. The waters are searched for the culprit. Along the way there is a discovery - namely, that little is known about tiger sharks. The result? A serious study of the species, which is reconstructed in "Beyond Fear".

Taking the Shark Week theme and running with it, host Steve Watson and company take apart an ordinary house and put it back together as a house sharks would die for - complete with a multichambered tank.

Better them than us. A team of divers tries to photograph great white sharks - as many as six at a time - with nothing between them but water and wits. The scene takes place over nine days off a remote Mexican island.

The bull shark: nine feet of pure brawn, one of the most aggressive animals on Earth. Bulls don't fear man at all and enjoy hunting in the shallows.
