An ancient, formless awareness beneath a forest clearing gradually becomes conscious of boundaries after first contact with a human child, learning the difference between surface and depth, self and other. Over centuries, as a house is built above the thinning and generations pass through it, the presence studies human containment, death, and grief, attempting to understand connection by mirroring those who enter. When it finally tries to complete a long opened hinge with the child grown into an adult, it is instead taught the meaning of separation, consent, and loss, forcing it to confront its own solitary existence.
