Freema Agyeman narrates a documentary series focusing on the most extraordinary and eye-watering cases to come through the doors of a British A&E department. Featuring a man who has a slip with his scissors while undertaking some 'pubic topiary', an oil rig worker airlifted from the North Sea when he swallows a toothpick and a victim of 'frozen food injury'. Plus, bloodsucking leeches are stuffed into a woman's mouth to keep alive her transplanted tongue.
