The Zero Imperative (home video)

Synopsis
Former UNIT luminary Liz Shaw and her assistant Bayliss are investigating a series of bizarre murders, all committed near a soon-to-be-closed psychiatric hospital.

When the hospital is unexpectedly reprieved by rich Industrialist Peter Russell events seem to move out of Liz's control. Are the incumbent director of the clinic, Doctor Dove and his predecessor Doctor O'Kane harbouring the killer? What is the centuries-old horror hidden in the grounds?

And what exactly is the secret of room zero?

Story notes

 * This film marks the debut of the Preternatural Research Bureau (PROBE) and the return of Caroline John as Liz Shaw. Other actors from Doctor Who -- including John's former co-star Jon Pertwee -- also appear, but in different roles.
 * This is the first of four films featuring the PROBE organization. As such, it predates Torchwood as the first ongoing spin-off of the Doctor Who universe.
