A head teacher's work is never done, especially if, like Jane Cowan, you're a victim of your own success.
Having done well with Wrayford Primary, she's now expected to bring other neighbouring schools up to scratch as well. And all these responsibilities are compounded by an influx of children, most of whom do not speak English, following their families supplying cheap labour to surrounding farms.
Jane can't turn a blind eye to the conditions in which many of these families are living, even more so when some children simply disappear.
When everything points to the shadowy dealings of people smugglers in the area, she has her work cut out for her seeing justice done. And that's before a threat far closer to home rears his head.
