An industry film for the West German Post Office. The use of the latest communications technology to link up the world. A technophile ballet in the mysterious world of relays, very high frequency channels and decimeter bridges. 觀感極佳,視與聽,光與影。一看導演原來是Edgar Reitz!幾個場景想到物理實驗課。$觀感極佳,視與聽,光與影。一看導演原來是Edgar Reitz!幾個場景想到物理實驗課。
