British Comedy Award winner Kayvan Novak (Facejacker), Rhys Thomas (Star Stories) and Richard Madden (Game of Thrones) star in a series from Brian Fillis (The Curse of Steptoe, An Englishman in New York), inspired by Tom Reynolds' book Blood, Sweat and Tea.

To the outside world Stuart (Thomas), Ashley (Madden) and Rachid (Novak) look like angels of mercy; to their colleagues, they're a trio of pedantic know-alls; and to the career alcoholics and late-night revellers on the swarming streets of Leeds, they're nothing more than glorified taxi drivers with one drop-off point - Accident & Emergency.

Rhys Thomas (best known as a spoof talk radio presenter on Bellamy's People) plays Stuart. At the end of a shift, Stuart just wants to go home, lock the door and keep the other naked apes out. Those misanthropic tendencies are the source of ongoing friction with Maxine (Amy Beth Hayes; Misfits), a sergeant in the West Yorkshire police force and, to all intents and purposes, Stuart's only friend.

Kayvan Novak (who picked up the Best British Comedy Performance in a film for his role in Chris Morris's Four Lions) is Rachid - a man with a naughty past that's always threatening to catch up with him. Behind the sexual conquests and non-stop boasting about his prowess, Rachid's biggest worry is the niggling self-doubt that the girls he sleeps with only ever view him as an exotic sideshow and never the main event.

Richard Madden (Worried about the Boy) plays Ashley. Young, handsome, and a bit of a lad, he thinks he has it sussed, knows how to play the game, and always keeps his cards close to his chest. His only problem - as a gay bloke who doesn't actually like other gay blokes - is that he's never in the biggest game of them all.

Swept along by an endless tide of bodily fluids (rarely their own), the trio bicker, fight and shag their way through the darkly funny maelstrom of their lives. Behind the uniforms, the sirens, and the fast driving, they are three ordinary blokes trying to make it through yet another shift.

But once they've finished saving other people's lives, will they be able to salvage their own?
