A series of unexplainable accidents befall the people and companies responsible for developing the world's first supersonic airliner (SST1). A British agent is sent to investigate and with the help of another agent uncovers a plot masterminded by Carl Petersen who stands to gain eight million pounds if the aircraft is not ready by a certain date. The evil Petersen has developed a number of"robots" (actually rather beauti***irls with"electronic brains") to help him sabotage the SST1 project by means of"infrasound" (extreme low frequency sound waves) which can be directed at people or objects with devastating results.
