Overview: Charlotte’s Hell On the internet, they’re known as trolls. But let’s name them for what they really are – bullies, plain and simple. These cowards lurk in the shadows of the online world, using false names to spread their messages of hate. Their attacks can be vicious, intensely personal and, with the growth of social media like Twitter and Facebook, dangerous as well. Just days ago, television celebrity Charlotte Dawson was pushed to the very brink by these creeps. She was still shaken when Tara Brown spoke to her but she somehow found the strength to share her story. Her hope is that by speaking out, she can save someone else from the Hell that she only just survived. Reporter: Tara Brown Producers: Stephen Taylor, Hannah Boocock DIY Mums They’re the newest and most controversial operators on the fertility scene. Private sperm donation websites operate like online dating services, matching up would-be mums with donor dads, for free. Unlike traditional sperm banks, the woman actually gets to meet the potential dad. And he’s encouraged to become involved in his new baby’s life. This is a do-it-yourself method of getting pregnant so it’s light on romance and there are possible health risks. But, as Allison Langdon discovered, it’s also produced lots of little love stories and some very modern families for the mums brave enough to try. Reporter: Allison Langdon Producer: Jo Townsend Licence to Thrill His name is Bond. James Bond. And he has to be the coolest chap on the planet. He’s triumphed over scores of unforgettable villains, bedded hundreds of beautiful women and saved the world over and over again. Fifty years have passed since Sean Connery first shrugged on a dinner jacket and ordered his martini shaken, not stirred. And now we’re gearing up for movie number 23. “Skyfall” stars the famously muscle-bound Daniel Craig. And no doubt, it will be another blockbuster for a franchise that’s become one of the most successful in movie history. Reporter: Charles Wooley Producers: Danny Keens, Sandra Cleary The Great Escape On Sunday night you will witness one of the most extraordinary acts of survival you’ll ever see. Ken Peters was performing in a show at Sea World in San Diego when a killer whale suddenly turned on him. For the next ten minutes, Ken was locked in a life-and-death struggle with the three-tonne predator. It’s incredible that he kept his composure and made it out of that tank alive. Others haven’t been so lucky. Reporter: Michael Usher Producer: Stephen Rice
