Jack and his dad are runaways. Jack's father recently turned whistleblower, revealing the truth about the illicit dealings of some powerful people. Realising that he and Jack might be in danger, Dad drives them to a remote shooting lodge in the Scottish Highlands, where they intend to lay low.

In the cornfield beside the lodge stands a scarecrow. When Jack witnesses something incredible, he begins to realise that it is no ordinary scarecrow - it is alive, hungry and fuelled by rage. And when Dad's enemies begin to converge on the lodge, the scarecrow might just turn out to be Jack's best hope of survival.
