In an atmosphere of a "state of the art mediocre German early evening television crime serial" a totally different kind of story is evoked. These yuppies start dancing at the seemingly empty office building in the after hours. Only the cleaning woman is there to witness the strange activities. But is she really there? And is she there, then when they are there? Breathing becomes heavier. One can hear, almost feel every movement. It is the sound - the constant threatening sound that keeps one alert. Combined with an excellent performance by the dancers.
