Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.

Alien Heart was the first of two stories comprising the two hundred and twenty-fourth release of Big Finish's monthly range. It was written by Stephen Cole and featured Peter Davison as the Fifth Doctor and Sarah Sutton as Nyssa.

Coincidentally, Alien Heart was set during the Dalek-Movellan War, a conflict revisited on television in The Pilot just four days prior to this story's release.

Publisher's summary[]

In the TARDIS, the Doctor and Nyssa stumble across a trail of ten destroyed worlds, all of them obliterated by means of some utterly monstrous but utterly unknown device. The planet Traxana would seem to be next in line to suffer the same fate. But when the TARDIS lands on an outpost on Traxana's moon, Nyssa is carried away by a tide of giant green arachnoids, leaving the Doctor behind...

And the coming menace is closer than he thinks.
