After inheriting her late father’s house, Mara Ellison discovers strange disturbances in his backyard where he had obsessively dug before his death. Finding his journals marked with the phrase Dig Within First, she unearths a buried wooden box containing only a mirror. When her reflection begins moving independently and accusing her of abandoning her father, buried guilt resurfaces. As the ground outside mysteriously shifts and expands, Mara realizes the digging was never about the soil but about confronting suppressed regret and unresolved love. To stop the haunting unrest, she must face the truth within herself before the hollow ground consumes her completely.
