Horst is a hunter trying to stave off the inevitability of aging. Futile, as we all know. Nevertheless, he suffers a crisis of identity about himself, his world, and the forests and glades he so loves. Two days after the disappearing of his dog Birko, Horst plunges deep into the forest to try and find him, and in doing so, re-immerses himself in his beloved natural world. He hears barking and ploughs on, in search of Birko. Deeper and deeper he goes. What will he discover, deep in the bosky depths?
