In the south of England, at an isolated laboratory near a small village, physicist Dr. Laird (Alec Mango) is assisted by American scientist Gilbert Graham (Forrest Tucker). They are performing a series of advanced and dangerous experiments with magnetic fields, while using massive amounts of power in equipment never designed to carry such loads. An accident occurs and injures another assistant, after which a request for a replacement sent to the Ministry of Defense brings Brigadier Cartwright (Windham Goldie) down to investigate. He is accompanied by a woman computer expert, Michele Dupont (Gaby Andre), who helps to solve Laird's power problem, but not the larger risks inherent in his experiments.
