Paramedics from the Special Operations Response Team are called to a remote canalside in Stirlingshire, where a young walker has slipped and dislocated her knee. As night falls, the team need to scramble their specialist all-terrain vehicle to transport her from the canalside to the ambulance. On Skye, ambulance crews need to be prepared to transport patients long distances to and from hospital. Georgia and Paul attend a patient who has Covid-19 and is having great difficulty in breathing. The crew suspect she may be suffering from a pulmonary embolism and need to get her to hospital in Inverness – a three-hour drive – as quickly as possible.
