It begins with the normally healthy Beth – aged-care worker, wife of David, mother of Lettie and Gem – feeling vaguely off-colour. A locum sends her to Dr Yi for some tests.
'There are a few things here that aren't quite right,' says Dr Yi, 'and sometimes it is these little wrongnesses that can lead us to the bigger wrongs that matter.'
Beth is sent on to Dr Twoomey for more tests. Then to another specialist, and another. Referral after referral sees her bumped from suburb to suburb, bewildered, joining busloads of people all clutching white envelopes and hoping for answers.
But what is actually wrong with Beth - IS anything, in fact, wrong with her? And what strange forces are at work in the system?
