A woman from Nigeria recovers in the hospital after going into premature labour with quadruplets having fallen ill on a flight. She receives a visit from the hospital's overseas officer Terry, whose job it is to prepare her for a huge bill. Because she is not a British resident, she must pay for the care that she and her babies are receiving. The cost of such specialist care quickly tops £100,000 and looks likely to rise to half a million pounds during their stay. Terry explains that, despite her distressing predicament, it is a legal requirement for the hospital to collect the money the NHS is owed. The woman is just one of a number of overseas patients who are receiving lifesaving care and from whom the hospital must now try to recoup money. Although emergency treatment given in A&E is free, non-UK residents who are admitted to a ward have to be billed.
