The brand new series of the RTS award-winning documentary continues to follow patients treated in the same 24-hour period at St George's Hospital in south-west London, which has one of the most advanced and busiest A&E departments in the world; it's a place where stories of life, love and loss unfold every day. Stephan, who is 39 years old, is rushed to St George's with internal bleeding from his femoral artery. Stephan has a condition called Sudden Arrhythmic Death Syndrome and the bleed was caused by complications following an angiogram he had the day before. Doctors are concerned that the drop in blood pressure and sudden blood loss could be putting Stephan's heart under potentially fatal strain. Stephan had to have a device fitted to restart his heart and his cardiologist encouraged him to 'live a little' - so he's in training for his first Iron Man event. Emmanuel Junior, who is 19 years old, comes to A&E after suffering an acute attack of sickle cell disease.
