Psychedelic Electrical Storm
The Master has been up to his old tricks again. After bringing the seemingly helpful Axons to Earth, it turns out that all they wanted was to feed off the planets energy while the Master planned to steal the Doctor's TARDIS. Having been thwarted by UNIT, the Master comes up with a scheme to blow up the Axon's ship before it destroys the world, but the Doctor and Jo are inside. Will they make it out in time?
