Classic Doctor Who: Galaxy 4

On a desolate planet, the Doctor and his companions encounter the all female Draahvins and their leader Maaga whose ship has crashed there.

Intent on capturing the repaired spacecraft of the hideous Rills, Maaga holds Steven hostage and forces the Doctor and Vicki to go to the Rill ship.

The Doctor and Vicki learn the truth about the Drahvins from the ammonia breathing Rills. Meanwhile, when Steven attempts to escape the Drahvins, he finds himself in more peril.

As the planet faces destruction, Maaga launches a final attack on the Rill base. The Doctor offers to transfer power from the TARDIS to the Rill ship so that it might escape.
