Sarah Jane Smith, Clyde Langer, Rani Chandra and Luke Smith are in Sarahs loft, checking something on the computer.
Mr Smith, Sarahs computer, announces an unknown force is locking on to the attic, Ronnie Corbett teleports in, he introduces himself as Rani, an ambassador for the galactic alliance, and makes a Two Ranis joke.
Ronnie Corbett sits down to tell a story, but he starts making gas emission noises, K9 teleports in talking about a Slitheen, Ronnie Corbett wheel-clamps K9 and reveals himself as a Slitheen, and he has come to steal K9!
Using her sonic lipstick, Sarah attacks the Slitheen, Mr Smith teleports it away, K9 says affirmative!
I hope to have an international embeddable version of this soon :)
It doesn't look like there will be a Planet of the Dead trailer, but there is only 4 weeks until its Easter transmission though :)
