February 2012. Somewhere in the North Atlantic. In an increasingly uncertain defence environment, a deadly new arms race has begun. In an attempt to secure her boundaries, Britain has deployed the very latest sub-sea military technology. Beneath and beyond the front line, these are the adventures of the HMS Goliath. A 55,000-tonne M-Class nuclear stealth submarine, prowling 5,000 metres below the surface, manned by idiots.

Welcome to Concrete Cow, the sketch show where anything is possible. Written by James Cary, who won a Silver Sony Award for Think the Unthinkable, this silly, surreal and ingenious comedy stars one half of ‘Mitchell and Webb’, Robert Webb. Also featuring are Oscar-winning actress and comedian Olivia Colman, as well as Sally Hawkins, Chris Pavlo, Beth Chalmers and more.

Composed in the early 1350s, in the wake of the Black Death, The Decameron comprises 100 short stories from all over the world, reset by Boccaccio among the flourishing merchant classes of Renaissance Italy. Their universal themes—love, sex, religion, fate, morality—resonate with us to this day, and their witty, satirical, bawdy voice sounds utterly modern. Monty Python star and medieval historian Terry Jones presents ten BBC Radio dramatisations of tales from Giovanni Boccaccio's humane and comic masterpiece

In this Christmas special 'Molokai' - It's Christmas morning, but when Carolyn schedules an extra stop-off to the Hawaiian island of Molokai, Arthur has just seven minutes to celebrate Christmas.

Welcome to the inside-out world of Mitchell and Webb, a strange and surreal place populated by misfits, eccentrics, talking animals and a few stray Radio 4 arts programme presenters. Included here are all five series of their fantastically skewed comedy show, packed with offbeat sketches and peculiar characters. Meet seedy snooker commentators Ted and Peter; poorly matched crime-fighting duo Angel Summoner and BMX Bandit; a cop who doesn't get results but, by God, he does things by the book; and some nervous Nazis who've just noticed their caps have skulls on them.
