Joan Leeton was certainly a lovely girl. A perfect girl for an English scientist to fall in love with. Unfortunately for Will Fredericks and Bill Josephs that's exactly what happened, to both of them - and to the same girl too, Joan! But they were no ordinary scientists, and they created the most marvelous invention. A device that could perfectly replicate anything. But could it replicate a lovely girl named Joan Leeton? Could they create a love triangle with four people?
