Freema Agyeman narrates a series focusing on the most extraordinary and eye-watering cases to come through the doors of a British A&E department. Includes a man with bizarre ballooning lips; a frustrated farmer with an obliterated knee, courtesy of a runaway sheep; and a mechanic who has carved up his finger in a car fan belt. Plus, the stomach-churning story of a DIY enthusiast who nearly died after excavating his intestines with an angle grinder.
