During one of Nyssa's experiments, the TARDIS's temporal scanner picks up a message: 'Idra'. Just one word, but enough to draw the Doctor to the Archipelago of Sirius. There, the Autarch is about to announce a new crusade. A mighty war against Seth, Prince of the Dark. But who is Seth?

Four-part adventure for the fifth Doctor (Peter Davison). When the TARDIS is drawn by an irresistible force to the hostile and barren planet of Frontios, a gruesome fate awaits the spacecraft's crew and the planet's last few surviving humans as alien parasites, burrowing undetected below the planet's crust, prepare to devour them.

You are cordially invited to Argentia, the galaxy’s most exclusive tax haven, to attend the funeral of mining magnate Carlo Mazzini.

Can the Doctor, Nyssa, Tegan and Adric apprehend the murderer before Argentia – and everyone on board - is forever cut off from the rest of the Universe?
