Brian, an engineer on an oil rig, is airlifted by helicopter to the hospital with suspected serious neck injuries. It is an urgent case for Dr Lalla and his team in accident and emergency because, aside from his injury, Brian has a worryingly low heart rate which requires thorough investigation. Coastguard and lifeboat teams are scrambled to the aid of a pleasure boat whose propeller has been fowled just feet from Shetland's jagged rocks. The ambulance team race to the aid of a former nurse with a suspected stroke. Back in the hospital, one of Europe's strongest men comes in with an injury that has come about because of his incredible strength.
