3.3 The Creeping Death
London, 1952, and a deadly smog envelops the capital. But something even more dangerous – and alien – is hiding within the mists.
When the Doctor and Donna get lost in the fog, they find a motley group of Londoners trying to make their way home.
Soon the stakes are raised, as death creeps along fume-choked streets, and not everyone will make it out alive...
