This one-off special episode of the BAFTA winning hospital drama returns to the wards and sees the dysfunctional team's drama-fraught lifestyle continue apace. Caroline (Tamsin Greig) is now engaged to Guy (Stephen Mangan), while Mac (Julian Rhind-Tutt) has very little time to live. Gripped by desperation and paranoia, dwarf-killing duo Statham (Mark Heap) and Joanna (Pippa Haywood) are on the run, jumping relentlessly out of frying pans and into fires (not quite literally). With no one left in charge, the admin girls let their basic instincts run wild, while something very strange has happened to Karen (Lucinda Raikes) after her fall from the window. Boyce (Oli Chris) discovers life without Statham, Sue White (Michelle Gomez) spots a job opportunity and Martin (Karl Theobald) feels utterly helpless. Again. Still, at least it all ends happily ever after. Or does it?
