In the heart of an underwater cavity - the Bushman Hole - a diver sets out to find a colleague who died ten years earlier. At the end of this ordeal, he ends up discovering something else.

The structure of the piece follows the thread of his path :

first, the great leap into the depths, symbolized by the ambient noise. Then, the pulsation of the drums, like a heart that beats faster and faster, reproduces the tumultuous crossing. Finally, the harp, with a bewitching melody, accompanies the diver in a last sigh, lulling him to his final encounter.
