Highly-charged documentary following London's elite trauma team, Medic One. The team are deployed by helicopter and high-performance cars to major accidents across the capital, and they deal with major traumas at the scene. Every day they are called to deal with car and motorbike accidents, stabbings and shootings. The doctor and paramedic partnership is a 'mini A&E department', equipped with powerful drugs, monitors and even kits to perform open chest surgery on scene. For Medic One, getting in there on time really is a matter of life and death.
