Caught in a time corridor, the TARDIS is drawn to an abandoned warehouse
in London, 1984 where the Doctor, Tegan and Turlough encounter a bomb
disposal squad investigating the discovery of mysterious alien objects.
In the far future, the Daleks and their human mercenaries attack a space
station prison to release Davros, who has been frozen for ninety years.
The Daleks have lost their war with the Movellans and require a cure for
the virus that is destroying their race. Davros, however, has other plans
for his creations.
As the Doctor fights to prevent the Daleks from carrying out their evil
schemes, even the TARDIS crew cannot escape untouched by the tragic events
unfolding around them...
