Professors Vrooshka and Crump decide to visit an archaeological site to study the artifacts there. Lo and behold, it's right next to a caravan site where all manner of people are staying. With a randy Major owning the site, a snobbish mother, and the two professors' constant innuendos, the film ends with a sinking caravan site and a striptease performance as a replacement for the cabaret night.

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 beautiful girls 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.
