It uses a sci-fi theme of parallel universes to poke fun at life and especially the media business in London.

Would-be journalist Edna Turner comes to London to work on the listings magazine Get Out!, a parody of Time Out.

She encounters Tankerton Slopes (Ben Moor) who works in a parallel version of London called Undone.

Tankerton sends Edna to check out unusual events and places that may be the results of people crossing over.

In the process, she perceives even more universes, including one in which she is "a fictional character played by Sarah Solemani".

Returning to her flat, she wonders if she imagined everything, but sees the gifts Tankerton gave her, and discovers she can cross to Undone simply by concentrating.

She also learns that they are half sisters and their father is The Prince (Kevin Eldon), a man who wants to unite all versions of London together and thus is an enemy of Tankerton.
