After the sudden death of her father, eight-year-old Simone (Morgana Davies) shares a secret with her mother Dawn (Charlotte Gainsbourg). She’s convinced her father speaks to her through the leaves of her favourite tree and he’s come back to protect them.
But the new bond between mother and daughter is threatened when Dawn starts a relationship with George (Marton Csokas), the plumber, called in to remove the tree’s troublesome roots. As the branches of the tree start to infiltrate the house, the family is forced to make an agonising decision. But have they left it too late?
