Lifelong friends Harry and Karl (David Mitchell and Robert Webb) are the greatest magic double act in the country. But after a guillotine illusion goes horribly and spectacularly wrong, their friendship and their careers are finished.

Now, down on his luck and out of cash, Harry sets his sights on the prize money of the prestigious 'International Magic Shield' tournament. But to win he will have to compete against the world's oddest magicians - including his deadly rival Karl, performing under the guise of ridiculous psychic 'The Mindmonger'.

Can new tricks and a new assistant help Harry to triumph over his underhanded opponents and his disastrous past?
