In Melbourne, 2018, Imogen is bewildered when a mysterious stranger says her grandfather in New Zealand needs her help. Her grandfather is dead - isn't he? Imogen, a former journalist, decides to investigate and travels to Taranaki where she finds someone is trying to frighten the old man off his farm.

A long shadow hangs over her grandfather's land - from 1864 when two young Irishmen join the British army in its fight against the Taranaki Māori, to 1975 when Imogen's grandparents arrive, fleeing trouble in Ireland.

Their daughter Aoife - Imogen's mother - hates the new country her parents have brought her to, yet she knows it is impossible to return. The Irishman she encounters in a hedge, is as lost as she is.

Ghosts haunt the present, while the land holds its secrets close. Yet some secrets won't stay hidden in the past.
