In the heart of a mysterious forest, a woman wakes from trauma, lost. In her search, she finds the Spine, a special tree where everything began and ended. Under the rain, looking back, she glimpses the shadow of the man who left her, and trying to discern reality from hallucination, she faints. Upon waking, she questions herself: was it all a dream? Spine is the backbone, the foundation. Are you lost or are you finding yourself?
