Hopes are high when a message is received by neutrone transmission from Earth. But though the Moon has been in outer space for only a few months, it is 2120 A.D. on Earth. The message comes from a Texan space scientist named Dr. Charles Logan, who explains to the alphans some technology which will give them one opportunity to return to Earth. Koenig decides that he, Helena and Alan Carter will test it out before returning the entire crew to Earth. This cautious move is proven very wise when somehow the three of them arrive on Earth in 1339, in Scotland, which is engaged in civil war against England!
A neutrino transmission is being transmitted to Alpha from an unknown source. When asked to identify themselves, they reply that they are from Texas City, planet Earth!
Dr. Charles Logan tells the Alphans that a galactic eclipse is moving between the Moon and Earth in 72 hours, but if they act quickly, and do as he says, a return to Earth is possible.
The Alphans are thrilled at the prospect, but Koenig is not sure that the message is from Earth. When Logan asks if they are ready to start work on the Transference Dome, Koenig tells him no. He asks a few questions to see if he really is from Earth. The rest of the Alphans start to bristle, but Logan answers the questions with no problems, and Koenig agrees to start work on the apparatus.
Carla begins to tell them of the the Earth of 2120. Mankind has been forced into domed cities by the pollution of the 21st century, but with the use of their "personal telesensual systems" can create the illusion of spring in the Rocky Mountains or fall in old New England, at the touch of a button.
Construction of the Tranference Dome is completed quickly and they are ready to test the procedure. A test package is conctructed to simulate vital signs, and transmit the readings to back to Alpha.
The package is transferred back to Earth without a hitch. Now it is time to try the procedure with people. With a limit of three people at a time, Koenig ask for two volunteers to go with him. Helena and Alan join the party. An earthquake strikes as the transfer begins, disrupting the process. Koenig, Helena, and Alan disappear from Alpha, but do not appear in Texas City. They do, however, appear in a lush wilderness. The question is, if the Earth is uninhabitable outside the domes, where are they?
As they explore, Alan is attacked by a man with a sword. Koenig manages to save him, but when they go back for Helena (who is quite ill), they find that she has been captured, and are taken as well. Back on Alpha, they're recieving data from the medical monitors. Knowing that they are alive somewhere, they are trying to locate their lost comrades.
Dr. Logan has a team set explosive charges to recreate the conditions that threw off the transfer process. He figures that if they can recalculate their location they can be returned to Alpha by reversing the magnetic field on the projection pods on Alpha's Tranference Dome.
Meanwhile, Helena's temperature is rising. She sees a fungus that is the basis for a cure growing on the wall of their cell, but they need fire to heat it. Koenig and Alan create a ruckus, drawing the gurds into the cell. As Koenig startles them with the light from his medical monitor, Alan jumps one of the guards, then John takes the other. They escape to the woods, and while preparing the medicine, Helena sees the Moon.
John thinks that she is delirious and starts to give her the remedy. Alan and John look and realize she is right. They must be on Earth at some point in time before the Moon left orbit. They are recaptured and brought to the table of the lord of the castle. He asks why three Englishmen would be wandering through the forests of Scotland. When he learns that Helena is sick he assumes that they have been turned out by some English lord because she has the plague. And to prevent the spread of disease to his people, he commands that they be burned.
They are shackled to a wall, and as a pyre is assembled before them, Koenig tries to send a message to Alpha in morse code by clicking Helena's monitor on and off. The message is recieved on Alpha, the "old" code recognized, and decoded by the computer.
The information is then passed on to Logan. He has Carla recallibrate the transport coordinates for Scotland in 1339. As the flames rise, Koenig, Helena, and Alan are transported back to Alpha.
Logan contacts Alpha to tell them all communication channels will be closing. Koenig says goodbye and thanks Logan for trying, just before the eclipse severs all communication between them.
John visits Helena in Medical Center. She says it was a shame that, of all times, they landed in 1339 Scotland. John lists a few worse possibilities, and Helena replies "With a history like that, who wants to go back to Earth anyway?"
