Lurking beneath St. Etheldreda's hospital façade is a secret subterranean world. A world of endless corridors, party-throwing mortuary attendants and baton-happy security guards.
This is the part of the hospital the public never gets to see - an underground community of hospital workers making the world above them run like clockwork(ish).
Moving between the two worlds - the glue that binds everything together - are the porters. Whether it's a urine sample, a complaining patient or a dead body - if it's in St. Etheldreda's, you'll need a porter to move it.
Written by Dan Sefton and inspired by his own experiences of working in a hospital, Porters features deluded Simon Porter (Easton), who dreams of passing his medical exam and becoming a doctor - but by starting at the bottom, and becoming the best porter the NHS has ever seen.
All he has to do is survive a few months grafting in a hospital basement and try not to kill any of the patients. How hard can that be?
The stellar supporting cast features Karma-loving, German-born Tillman (Rutger Hauer), self-styled "Queen of the Porters" Frankie (Susan Wokoma) and naïve nurse Lucy (Claudia Jessie) who Simon falls hopelessly in love with.
Also roaming the hospital corridors is battle-hardened but exhausted Dr Kelly (Jo Joyner), hypochondriac patient Mark (Mathew Horne), highly mischievous transplant surgeon Mr Pradeep (Sanjeev Bhaskar), and ruthless NHS manager Jane Bison (Tanya Franks).
