When Rachel is admitted to the emergency department after a head-on collision with another car, trauma team leader Anthony Taylor fears the worst. Trapped inside her vehicle for over an hour, Rachel's condition is now critical. Anthony and his team know that time is of the essence. But before they can get her to a much-needed scan to assess the extent of her broken bones, her breathing deteriorates and it's a race against time to stabilise her and save her life. Across the hospital, Sally has been rushed in for emergency surgery. During a routine mammogram, it was discovered that Sally not only had breast cancer, but also an aortic aneurism. Already at twice its normal size, Sally's aorta is in grave danger of rupturing — which could prove life-threatening. Now Mr Warwick and his surgical team must navigate the risk of stroke and organ failure to perform complex open-heart surgery to give her the best chance of survival so she can begin her cancer treatment. Back in the emergency department, Shaun arrives as an emergency transfer from another hospital, after scans revealed multiple broken bones following an accident on his electric mountain bike. However, after examining Shaun, trauma team leader Richard Hall fears that he has yet more lifechanging injuries — potentially to his spine. The race is on to get him to an operating theatre quickly and safely. Finally, trauma team leader Diane Adamson treats Geoffrey, an 88-year-old farmer who has been attacked by one of his cows. Knowing a farmer's capacity for pain, she's on high alert. So when Geoffrey starts complaining of chest pain, Diane knows she will have to act fast before his condition deteriorates further.
