Rick is at his lowest ebb. With no other work on offer, he decides to set up his own stand-up comedy workshop. But the first week's class attracts just five students. Worse still, the second session includes a new wannabe comic - deranged cafe owner Michael. A disastrous session on how to deal with heckling backfires spectacularly, but hope is on the horizon - in the form of an earnest council executive, Libby.

Meanwhile Magda is trying to claim compensation after tripping on a paving stone, but it turns out that Rick is the one who's in danger of serious injury.

Having accepted funding from the local council, Rick reluctantly agrees to teach a Stand-up Comedy Workshop in Belford Prison. But this turns out to be one of Rick's worst gigs: he is taken hostage, trapped in the prison library by a knife-wielding prisoner, Donald. Donald is a worrying mixture of charming and psychotic - and worse still for Rick, has a pathological hatred of liars. Can Rick talk his way out of trouble? Will the governors give in to Donald's demands? Or will this be the end of Rick's less-than-stellar career?
