The storyline involves a team of scientists who use an incredibly strong magnetic field to open a door to another dimension.
The one thing they share in common is a wish to cross the Borderlands that lie beyond the Outer Limits.In an accident, Professor Ian Fraser encounters a magnetic field that reverses the form of living matter.
Knowing the cost, Fraser approaches Dwight Hartley, a wealthy magnate grieving over the loss of his son.
While experimenting on inanimate objects and small animals, Fraser is approached by Benson Sawyer, Hartley's managing director.
Unknown to either of them, Mrs. Palmer and her assistant Edgar Price have appeared at the power plant, and watch as Fraser's experiments proceed.
With Fraser within the magnetic field, Price shorts one of the plant's generators, electrocuting himself and Mrs. Palmer in the process.
Not knowing if he can be heard, Fraser shouts out his observations, that the world looks transparent, and that another landscape appears superimposed over it.
