Things are typically hectic in Ward 17 as Kylie is involved in a car accident after the end of a protracted stint at the hospital. After suffering minor injuries, Kylie struggles to treat the driver of the other car. Bron is nursing 16-year-old Jacqui Henderson, a fit, young runner who collapsed while jogging to school. Mitch soon discovers Jacqui has pericarditis — heart disease. It is unusual in someone Jacqui's age, especially as she is so fit. Meanwhile, Terri must deal with a patient's unbroken repetition of the same song but after getting the elderly woman to stop singing, her condition rapidly deteriorates.
