What if the trees could tell us secrets that could save our future?

Lilly’s life is turned upside down when the global pandemic hits. In one sweep, she loses her job as an airline steward and is forced to move to rural Oxfordshire and live on her grandparents' farm. From flying high to living low, she spends her days trying to forget and her nights haunted by dark dreams where old Ma Hakka leads her to the depths of despair.

Her first thought is to keep the strangely disturbing nightmares to herself, but as they mount, the desire to share is overwhelming. During a group therapy session, she discovers that she is not the only one to experience such dreams. With the help of her newfound ally, Margaret, Lilly uncovers a series of dream accounts spanning seven generations which ultimately reveals the source of her dream – the Signal tree.

As her understanding of local history unfolds and her knowledge of how trees cast old lessons within the patterns of their wood, she is able to experience things through a new, longer-term, tree perspective. Can this new knowledge help her to re-learn the ancestral ways and, together with family and friends, create a path to a better future for the next generation – Generation 8?
