Second programme in the series following the life-saving work of the medics of a mobile intensive care service for children. The highly specialised emergency teams from The Children's Acute Transport Service, CATS, make sure critically ill children who need intensive care get it, wherever they are.

A toddler's brain infection is spreading into his blood stream. Already critically ill, he needs to be moved from his North London hospital to Great Ormond street for specialist treatment; the RAF fly the team 230 miles to save a baby whose heart isn't working properly; meanwhile, a little boy's failing lungs have sent his blood pressure plummeting, and he too needs urgent intensive care.
