The Home Secretary asks Charles and Martin to devise a PR campaign to promote the highly unpopular proposed National Identity Card scheme, and, with the office telephones behaving strangely, the staff begin to suspect they are under surveillance by MI5, with Alison's resulting paranoia leading her to take the most drastic of steps.
After serving his prison sentence, Charles returns to the office to find that the firm's latest client is Dean Wheelwright, an artist hotly tipped to win this year's Turner Prize - if only he can be persuaded to accept the invitation to enter.
Charles and Martin are engaged by the US Ambassador to reverse the UK's growing hatred of all things American. Meanwhile, Jamie and Alison endeavor to help Peter Harrow, a long-standing client of Prentiss McCabe, who has grown tired of his "TV's Mr Nice Guy" image and is looking to change it for something a little nastier.
The staff at Prentiss McCabe are split into two teams to tackle both sides of the same issue: the future of the House of Lords. Charles' services are engaged by a Downing Street aide to work on reforming the Second Chamber, while those of Martin are engaged by a Member of the House in order to preserve it in its current state.
