Paramedics from the Special Operations and Response Team attend a major crash on the M74, along with emergency personnel from all over southern Scotland and northern England. It is the hottest day of the year, and as well as dealing with the aftermath of the crash, paramedics must work hard to make sure all their colleagues are hydrated as they battle stifling heat.
In Ayr, Dan and Michael are called to a suspected heart attack in a block of flats. However, when they arrive, it becomes clear the patient is intoxicated but otherwise in good health. The crew try their best to treat the man, but he does not want to go to hospital.
In Edinburgh, Tom and Donna are dealing with a man they suspect has taken drugs and who is found slumped outside a shop on Princes Street. However, despite the crew's best efforts, he too does not want to be taken to hospital.
At the ambulance control centre in South Queensferry, call handler Sarah is dealing with a patient who has apparently overdosed on street valium, while, in the Borders, Melrose-based crew Christine and Mike treat Alan, a pensioner proud of his once-vibrant social life, but who is now struggling to get out and about. The crew suspect he may have broken his hip and transport him to hospital for tests.
And, in Inverness, Stuart and Leslie need to get a patient with heart problems to hospital as quickly as possible.
