In Nation's case he did this via the BBC and a plague known rather wonderfully as 'The Death'. The show was called 'Survivors' and followed a group of people trying to make their way in a world changed beyond all recognition and the trials they face as they go about relearning the skills needed in order to, well, survive.
Lucy Fleming's Jenny Richards remaining as a lead for all three series.
Survivors first series concentrates on Jenny, middle class mum in search of her son Abby Grant (Carolyn Seymour) and engineer Greg Preston (Ian McCulloch) as the three slowly find each other and more in a world suddenly bereft of people. Of the three only the overbearing Greg seems to have the slightest idea about how to survive with Abby entirely fixated on her search for her son and the as wet as water Jenny left entirely at odds with the world.
By the time we arrive at series two our group has, by necessity, joined forces with one we had met briefly in the earlier series. Abby has left to continue her search for her elusive son and has been replaced by Denis Lill as Charles Vaughan. Cowed by the deaths of many of the group he led in series one Charles is a more sympathetic character than the single minded and driven Abby. Joining them in this new community is Charles' saintly partner Pet (Lorna Lewis) and the lazy, smelly, miserable and deeply unpleasant farm hand Hubert Goss (John Abineri).
Since I was a little kid I've had a love for this very British sort of post-apocalypse TV and literature; I just find it irresistible. It's one of those genres where it's easy to point out flaws, inconsistencies and errors and here it's no exception - the obvious 'Where are all the bodies?' question is easily avoided given the TV restrictions of the time - but Survivors real strength is that for the most part they try and treat the apocalypse in as realistic a way as possible. The actual survivors are woefully ill equipped to deal with the situation they find themselves in and make some spectacularly bad decisions. They are temperamental, selfish, gossipy, insecure, angry, unpleasant, helpful, loving and entirely human.
