It begins with just a few people falling ill. Another flu virus that spreads around the globe. And then the reports begin that people are dying…

When most of the world's population is wiped out, a handful of survivors are left to pick up the pieces.

Cities become graveyards. Technology becomes largely obsolete. Mankind must start again…

Big Finish's third box set based on Terry Nation's classic post-apocalyptic series, Survivors: Series 3 presents four new stories from the world of the original television programme.

Beginning in the early days of the plague, before focusing on the survivors of a decaying London, these new plays promise to be some of the most terrifying stories Big Finish has ever produced, as we again ask the question – how far would you go to survive?

1: Cabin Fever by Jonathan Morris

After weeks of searching for her son across a devastated Britain, Abby Grant and her allies head into London in pursuit of new leads. One of the party is quarantined, holed up with a fever. They remember the very first days of the Death, and the actions of a man called John Vincent…

2: Contact by Simon Clark

A lonely voice on the radio calls out across the ether. Maddie Price is a long way from home, but not yet ready to give up hope.

3: Rescue by Andrew Smith

When his friends' lives hang in the balance hundreds of feet above London, Jimmy Garland leads a daring rescue mission into the capital.

4: Leaving by Matt Fitton

Down on the coast, plans are being made to reach out across the world. It could mean a new beginning for some, and the long-awaited chance to return home for others.
