A Brave FaceIn this job, we’re constantly surprised and inspired by the strength of the human spirit. But Liz Hayes has never met anyone quite like Charla Nash. Two years ago, Charla was savagely mauled by a friend's pet chimpanzee. She lost her hands, eyelids, nose and lips in the frenzied attack. In fact, by the time help arrived, there was nothing much left of her face at all. It's a wonder she survived. But Charla wanted more than that - she wanted to live. And thanks to an extraordinary face transplant, and her own fierce will, that's just what she's doing.Reporter: Liz HayesProducer: Phil GoyenThe Crystal CaveMichael Usher has just returned from a spectacular and perilous journey to the centre of the earth, to a magical place known as the Crystal Cave. To reach it, Michael descended underground, deep into the deadly heart of a Mexican lead mine. The furnace-like heat and soaring humidity there can kill you in minutes. But when you see what Michael saw, you'll understand why it was worth every suffocating gasp for breath.Reporter: Micheal UsherProducer: Danny KeensManhuntHe's Australia's most wanted man and the most elusive. Malcolm Naden has been on the run for seven years, crisscrossing some of our harshest terrain. It seems every time the police get close, Naden slips back into the scrub and the shadows. He's becoming a legend of sorts - like those bushrangers of old. And just like them, there's a bounty on his head. But Malcolm Naden is no hero. He's a desperate man, armed and dangerous and he needs to be caught. But join this manhunt for a few days, as Charles Wooley did and you soon realise just what the police are up against.Reporter: Charles WooleyProducer: Danny Keens
