Meet Dr Anthony Webster and Dr Ruth Anderson, two pathologists attempting to live normal lives in an atmosphere of death, decay and seriously unpleasant smells. Anthony loves his chosen profession, finding every cadaver exciting and surprising: 'they're like Kinder eggs that have died'. Ruth, however, longs for a juicy murder mystery, instead of one routine autopsy after another.

The story so far: unfortunately, Burrows, the leader of the colony, has died on the voyage, so his number two, Brian (Nicholas Lyndhurst), is now in charge. He's a nice enough chap but no alpha male, and his desire to sort things out with a nice friendly meeting infuriates the colony's chief physician, Lillian (Vicki Pepperdine), who'd really rather everyone was walking round in tight colour-coded tunics and saluting each other. She's also in charge of Project Adam, the plan to conceive and give birth to the first colony-born baby.

A 55,000-tonne M-Class nuclear stealth submarine, prowling 5,000 metres below the surface, manned by idiots.

However, his attempts to project a 'New Labour' image cut no ice with Ruth, and the two are soon at each other's throats. 

Sir John Woodstock (James Fleet) is the Lord of the Castle and basically in charge of keeping order in the ramshackle medieval village. Although he hates all that torturing and usually lets the peasants off with a bit of community service. He lives in his huge but slightly falling down castle (but then it was built by the French, so what can one expect) with his daughter Anne (Martha Howe-Douglas) and very teenage son Henry (Steven Kynman). Anne’s best friend Charlotte (Ingrid Oliver) nearly always joins Anne on her constant quest to find fit men in the village. 

Reporters Charlie Palmer and Moog Johnson are supposed to be exploring the galaxy in search of unimaginable news. But the beauty of an infinite universe is that if everything possible happens somewhere, there's no need to actually go there to check.

Unfortunately, their terrifying boss at Inter-Galactic News, Korg, is on to them and won't tolerate their fake news any longer.

The year is 2099 and Professor Nebulous (Mark Gatiss, League of Gentlemen) is the director of eco-troubleshooting organisation K.E.N.T. - the Key Environmental Nonjudgemental Taskforce.
