Investigative journalist Sarah Jane Smith, one-time companion to The Doctor, is back for a third series of alien-busting adventures, from creator Russell T Davies, which also features a special appearance from The Doctor himself, David Tennant, who stars in two episodes.

Sarah Jane is accompanied by her adopted son, Luke, his streetwise pal, Clyde Langer, their schoolmate, Rani, who lives opposite and has aspirations to become a journalist like Sarah Jane, and their Xylok super computer in the attic, Mr Smith. Sarah Jane's robot dog, K-9, also joins the gang on their adventures.

In the first of this two-part adventure, Sarah Jane and the gang face the most dangerous day of their lives, as the rhino-like Judoon return. When prisoner Androvax the Destroyer crash-lands on Earth, a Veil is set free and starts to turn Earth's technology against itself. And his next intended victim is Sarah Jane.

The series also features an extraterrestrial girl who can make people play games against their will; a living painting; the inhabitants of a supposedly haunted house; and monsters who want to infect Earth with a strangely aggressive weed. Finally, there is a chance for Sarah Jane to find personal happiness with someone who could be the perfect person to complete her family.

A brand-new website accompanies the third series, complete with a trailer maker, monster hunt, video diaries from the cast, web games and exclusive behind-the-scenes videos.

Sarah Jane and her gang, Clyde, Luke and Rani, are back on TV this autumn for brand new escapades. They'll be battling Judoon, Slitheen and Blathereen non-stop in what's set to be endless action and adventure. And watch out for a very special guest star this series!

Brand new series starts this October, only on CBBC.

Captain Jack Harkness, Gwen Cooper and Ianto Jones (John Barrowman, Eve Myles and Gareth David-Lloyd) return for a new adventure in Torchwood – Children Of Earth, a five-part series for BBC One.

An ordinary day becomes one of terror, as every single child in the world stops. A message is sent to all the governments of Earth: "We are coming." But, as a trap closes around Captain Jack, the sins of the past are returning and long-forgotten events from 1965 threaten to reveal an awful truth.

Torchwood is forced underground as the government takes swift and brutal action. As members of the team are hunted down, Britain risks becoming a rogue state. Meanwhile, the mysterious and powerful 456 draws ever-closer.
