Struggling with mental health, Merlin and his wife Lizzie leave the bustle of London and return home to a Cornish hill farm, where they discover that the damaged woods surrounding the farm are one of the UK’s last fragments of temperate rainforest. As they fall more in love with the rainforest, so begins a fight to save themselves, their farm and one of the world’s most endangered habitats.
