TARDIS rematerializes on the planet Dulkis, threatened by the two occupants,
Probationer Toba and Navigator Rago of the alien race, the
Dominators who with their deadly robot servants, the Quarks, have secretly
landed on an island. The Dulcians are pacifists and cannot retaliate. They
ignore the Doctor's warning and some of them are captured. The Doctor
discovers the Dominators' plan; to fire rockets down bore holes, causing
an eruption of the molten core planet. They will then drop an atomic
seed capsule down a bore hole, turning Dulkis into a radioactive mass,
thus converting it into fuel for the Dominators' space fleet. Jamie
and Cully, the rebellious son of Dulkis's leader, Director Senex,
become impatient and destroy a Quark. The Doctor and Zoe are captured
by the Dominators and taken to the Dominators' ship, along with the Dulcians.
The Doctor intercepts the seed capsule as it is dropped and conceals it
in the Dominators' flag ship just before it takes off. The ship
is then destroyed in an atomic blast in the air when the seed device is
activated. Back in the TARDIS the Doctor is forced to move quickly
as they are in the path of a lava flow. . .
commissioned as a six-part story, "The Dominators" suffered
a major re-write and was reduced down to five episodes by script editor
Derrick Sherwin due to the late arriving scripts.
All the episodes exist as 16mm telerecordings except for episode 3 which is a 35mm telerecording. All but episode 3 were held by the Film & TV Library when audited in 1978.
filming on Stage 2. (30 April - 1 May 1968)
2, 3, 5 - The zip on the back of Zoe's Dulcian
costume causes her quite a bit of trouble, as it comes undone on more
than one occasion (for example, when the survey headquarters is being
destroyed by the Quarks).
