WHEN THE WORLD SPEAKS, WHO WILL LISTEN...?At the edge of a forest, in the shadow of a mountain, a sentient tree grows.

As Sap thrives, she observes her new world - the beauty and the destruction. Formed from her trunk, powerful tools are milled and wielded by humans.

Sally Pringle picks up a violin, made from the dark wood of Sap, and a string of mystical manipulations occur.

Rebecca Pringle and her true love, Simon, are guided by a wooden figure, carved from Sap's own branches, in their dream of joining Medicines Sans Frontiers.

Susan Daily, a friend to the Pringles, documents their stories at Sap's desk, with Sap's pencil, on Sap's paper.

As the threads of their lives intertwine, Sap leads them, and humanity at large, towards salvation and away from self-destruction.
