Sylvester McCoy, Stephen Fry and John Sessions star in an action-packed adventure specially created for audio.
The Doctor and Antimony arrive on the planet Santiny, just as it comes under attack by General Tannis and his Canisian battle fleet. As the adventure lurches from Santiny to contemporary London and on to Gallifrey, it becomes clear that the Canisian's next target is Earth.
