A TV comedy drama adaptation of Going Postal, the then most successful novel in the "Discworld" comic fantasy series by Terry Pratchett. The magical Discworld is flat and resting on the backs of four elephants which are in turn standing on the back of Great A'Tuin, a giant star turtle of unknown gender.

Going Postal is the story of arch-swindler Moist Von Lipwig (Richard Coyle) and the beautiful, vengeful Adora Belle Dearheart (Claire Foy). A life long travelling con-artist, Lipwig's crimes finally catch up with him in Ankh-Morpork, the largest city on the Disc. Faced with death by hanging, Lipwig is spared by the city's ruler Lord Vetinari (Charles Dance), who sees him as the perfect man for the role of Postmaster in the decrepit Ankh-Morpork post office.

Faced with an almost impossible task, and making an immediate enemy of bloodthirsty tyrant Reacher Gilt (David Suchet), owner of the rival money-hungry Grand Trunk Clacks communication monopoly, Lipwig's first instinct is to run. That is until he meets the spellbinding Adora. Captivated by her beauty and brains, Lipwig will try anything to win her affections... little knowing the part he has played in her family's downfall.
