The RTS award-winning documentary series returns for a 13th run, following patients treated in the same 24-hour period at St George's in south west London. The hospital has one of the busiest A&E departments in Britain, which is under more pressure than ever. It's a place where stories of life, love and loss unfold every day. This episode features three young men from different walks of life. Shea, who's 17, is brought to St George's after a serious knife assault. With Shea's blood pressure becoming dangerously low, his mum Charmaine fears the worst. He's transferred to a high dependency unit as doctors worry that the knife has damaged his liver. Charmaine reflects on the terrible events of the day: 'I feel that actually there were two lives that day that were affected, I believe that he was as big a victim as Shea.' Bob's also 17. He's impaled his leg on a fence while taking a short cut home from his boy's school in London.
