A man prowls around the woods in the Alps. He lives in a World War I former stronghold. He appears to have a mission: he is the last agent of a secret society which for years has prevented the nuclear arms race to lead to the destruction of human kind. Clear-headed visions of the nuclear holocaust taking place on the horizon are his constant travel companions. Enemies are not easily recognizable, his certainties are lost, he stumbles in a world where the distinction between right and wrong is blurred. The bomb has become his obsession, his torment and his only reason to live.
