"Attempting to travel to Naples, the Tardis turns up in 1869 Cardiff instead - only to discover that a gaseous entity is possessing the bodies of the dead. Unsurprisingly, this causes serious problems for Gabriel Sneed, the local undertaker. For one of his corpses decides to pay a trip to the theatre to see Charles Dickens in action, only to ruin his performance as the gas exits the body and sends the crowd running for cover. Rose stumbles upon the now lifeless corpse being dumped in the back of the hearse, but is chloroformed by Sneed who quickly speeds off. The Doctor sees this and jumps into the bemused Dickens&amp;#039; carriage and convinces the bewildered writer to follow the hearse with some flattering persuasion. The pair soon enter Sneed&amp;#039;s abode and rescue Rose, with The Doctor working out that the alien beings travel via the pipes. Dickens remains sceptical and believes it to be trickery.  Meanwhile, Sneed&amp;#039;s servant girl Gwyneth reveals a psychic edge as she can see into Rose&amp;#039;s mind and thus the future. She senses a darkness within Rose and mentions a bad wolf... Gwyneth is quickly whisked away to be the medium in a sceance organised by The Doctor. They communicate with the gaseous beings who reveal themselves as the peaceful Gelth, claiming to be a dying species who need a physical host body. The Gelth say they entered Cardif via a time and space &amp;quot;rift&amp;quot; withn the city.  Despite Rose&amp;#039;s disgust, The Doctor believes it&amp;#039;s only fair to save the species by offering them the bodies of the dead to inhabit. Gwyneth goes to the basement to help open the rift as and allow the Gelth through. However, their true intentions soon become clear and The Doctor, Rose and mankind rely on the fleeing Dickens to have a change of heart and play the hero...
