The Fire Door explores the many unanswered questions surrounding a small child's trauma. When the directress of a rural New Hampshire preschool allows a silent little girl into her daycare, the realities of the child's tattered psyche become a mysterious burden. Annie Rotreno agrees to take on the challenge of reaching little Bree, with the help of a trauma therapist, and reluctantly opens her woodland safe haven to both the child and her terrified mother. As the journey of healing begins, a series of unexplained events takes place in the sleepy hamlet of Seacoast, New Hampshire, forcing Annie to seek out the help of her Chicago family to uncover the dark truths surrounding whom the woman and child are hiding from.
