Celebrating 50 years of Doctor Who, a brand new adventure for the Ninth Doctor. New Vegas, 23rd Century - a sprawling city huddling inside an artificial atmospheric bubble on a distant moon. Pleasure seekers flock there from every corner of the galaxy, to take in the shows and play the tables in the huge casinos.

But beneath the glitz and the glitter, organised crime rules the streets. Whilst Rose Tyler works as a waitress in the Full Moon nightclub, Jack Harkness poses as a reporter for the Daily Galaxy. Meanwhile the Doctor is helping the police department with their investigation into The Whisper, a strange vigilante who has been terrorising the city's underworld.

But the Doctor is also on a mission of his own - to save Police Chief McBain's life at all costs. Nicholas Briggs - the voice behind the Daleks - and John Schwab perform this original story by Cavan Scott and Mark Wright, with music and sound design.
