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. There's a circus dwarf who superglues his penis to a hoover; a shoemaker who stitches up her thumb; a boy who melts his trousers as he tries to put out a sparkler; and a toilet that falls off the back of a lorry and on to a man's foot.
