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…

Based on Terry Nation's cult post-apocalyptic drama, Survivors: Series 4 presents four brand new episodes from the world of the original television programme.

After the harrowing events of Survivors: Series 3, the new series finds Greg (Ian McCulloch) and Jenny (Lucy Fleming) out on the road, reaching out to other survivors on behalf of the Whitecross Community. Their journey will bring them back into contact with Jackie (Louise Jameson) and Molly (Fiona Sheehan) – and a new community headed by Theo, an inspirational leader played by Ramon Tikaram (UNIT: The New Series, The Prisoner, Happy Valley).

Survivors: Series 4 comprises four full-cast dramas, and also features bonus behind-the-scenes interviews with cast and crew.
