In the middle of an Irish peat bog, the inexplicable remains of a humpback whale are discovered by two rural women. Drawn into the mystery of how and why it has appeared, they soon realise the whale is exerting its own magnetic force; summoning the ghosts of lifeforms and ecosystems obliterated in the name of 'progress'. As the women explore its origins, they confront old divisions and differing views on the worlds gone before, and the worlds yet to come.
