Jimmy Kavanagh has a genetic condition where he absorbs and stores iron from his diet over and above the body's requirements - Haemochromatosis. He is unaware of this, but as time progresses, with increased iron levels, he exhibits many unusual traits: oxidation (rusting), becoming magnetised, and having strong bones (excess iron is stored in the bone marrow). Through various childhood experiences, he appreciates he's different but doesn't know why. After a significant event in which he saves Barbara, the woman of his dreams, from possible death, he realises he can control his magnetism. His life becomes further complicated after he comes to the attention of the KGB. They are interested in all things paranormal, and the CIA, which is determined to stop the Russians. Sheila further complicates Jimmy's life. Her father is Irish, though she was born in Australia. She has Haemochromatosis, but of course, from the Southern hemisphere, her polarity is reversed.

Will Jimmy and Barbara live happily ever after? Can he manage to thwart the Russians and the CIA? Since opposites attract, does his future lie with Sheila?
