This new sitcom comes from the brainpan of Dan Sefton, the medic turned writer behind BBC1's recent drama Trust Me, and features yet another character so desperate to be a doctor they will do pretty much anything. Ed Easton is the nervous new hospital porter who dreams of wielding a stethoscope, while his eccentric co-workers include Crazyhead's Susan Wokoma and former replicant Rutger Hauer. Kelsey Grammer also pops up for an irate cameo.
