Trouble is, Thermoman is not too familiar with Earth customs,so he is often embarrassingly honest and tends to take everything too literally. When he falls in love with nurse Janet Dawkins, his behaviour appears most peculiar to her family and colleagues. Thermoman met Janet when he rescued her from the Grand Canyon, but since then his mission to save the world from destruction often comes in the way of his earthly romance. Day-to-day, the couple have to overcome the conflicts that arise from Thermoman's double life. Did Janet really have to put his suit in the wash on the day when an abandoned space station was on course to destroy Grimsby? Should George stay for lunch with Janet's parents or fly off to stop an erupting volcano? Will George's life be worth living if he flies off? Even Thermoman can't be in two places at once, and his continually disappearing in and out of the toilet in Janet's tiny suburban flat or at the surgery is not easy to explain.
