This episode focuses on a young girl who is seriously injured when she's run over by a bus, as well as other pedestrians who've ended up as patients at King's College Hospital in south London. Twelve-year-old Jade from Kent is rushed 20 miles to King's after being hit by a car and knocked under a bus while walking to school. Her shocked mum Amanda travels with her in the ambulance, alongside a police officer. Doctors are concerned that Jade may have fractured her skull and could have internal injuries, so she needs an emergency CT scan to determine the extent of her injuries. Trauma consultant Des and a specialist paediatric team are on hand to deal with Jade's injuries and the staff are conscious that it's hard for her parents too. Just a few hours later, Des has his second road traffic victim of the day. Sixty-year-old Geraldine was on her way home from a shopping trip when she was knocked over by a car while trying to cross the road. Meanwhile, in minors, 40-year-old Brian has broken his ankle after falling while running for a bus. He's recently been released from prison and his electronic curfew tag is attached to his injured leg. His increasingly swollen ankle means it will have to be cut off. And six-year-old Linus has come in with his mum Polly after claiming to have swallowed a toy ring. And much to his mum's surprise, she finds out this isn't the first time he's consumed small metal objects.
