From the Radio Times:

7.35 Doctor Who
starring Sylvester McCoy
with Bonnie Langford
in Paradise Towers
The first of a four-part
adventure by STEPHEN WYATT
Paradise Towers won a lot of awards back in the 21st Century.  It might even be a nice place to live now, if it weren't for the Kangs, the Caretakers, and the strange behaviour of the Mark 7 Megapodic Cleaners.
