Something horrific will play out on our screens tonight as Channel 4 imagines a world in which Ukip win the 2015 general election.
Thankfully the nightmare vision of a purple and yellow future is confined to the realms of fiction - for now at least.
So what happens in 'Ukip: The First 100 Days'? Well, we've only been given a sneak-peek in the trailer above but needless to say it doesn't look good.
Oh lordy...
"You ain't seen nothing yet," says Nigel Farage and we fear he's right.

After rolling up to Downing Street puffing on a cigarette, Farage sets about withdrawing from the EU and closing the borders in scenes reminiscent of 'Children of Men'.
Then the riots start. Oh, and millions of people lose their jobs. Thanks Ukip.
The only predictable thing is that Nick Clegg looks pretty darn miserable.
Richard Bond from RAW productions, which made the film, said the party's policies were a "bit of an unknown" so the show concentrated on its most widely-publicised wishes which he said were "leaving the EU and having a robust immigration policy".
He said: "When we conceived of it Ukip were the big political story and had a quite extraordinary result in the European elections and I guess for us at that point we just thought 'What if?' What if that kind of trajectory was projected into the future.
"One of the toughest things at the script stage was trying to write something plausible whilst what was happening in the real world was sometimes implausible. The day Mike Read released the Ukip calypso we all looked at each other and thought we certainly wouldn't have written that and had we people would have said this is completely mad and insane."
Ukip: The First 100 Days will screen Monday on Channel 4 at 9pm.
