A solar tsunami sends the TARDIS hurtling towards a factory on earth where human doppelgangers are used to mine dangerous acid. A second wave hits and the 'Gangers' separate. Can the Doctor prevent an all out civil war between the humans and the 'almost people' before the factory explodes?

As the solar storm rages and the factory crumbles, a Ganger driven mad by the memories of being 'decommissioned' is seeking revenge. The Doctor must convince the terrified factory workers to embrace their own humanity and work together with their Gangers to overcome a monster of their own making.

When Eve Caleigh and her family arrive at Crickley Hall, they hope to escape the past. The past has other ideas, and the trapped ghosts that haunt the hall seem to be sending her a message that not only her son is alive, but that they know where he is.
