MIRROR WORLDS
The opening scene:
When a famous actor drops dead in mid-performance, the audience gasps...not of shock but of resignation that one of their finest talents is gone. The understudy comes on and picks up the line without missing a beat and the audience soon is immersed in the play again.
Such is the fate of the people on this world, in every way like earth except faced with the fact that people...anybody, could just drop dead suddenly. No warning...no illness or disease is necessary. Just dead...like that.
When researchers begin to study an astronomical anomaly, they soon discover that their world is a mirror world of another earth...our earth. They dub these two worlds as Earth Major and Earth Minor. Our world (Major) seems to hold a lifeline to the Minor world and when someone dies in Major, that lifeforce is gone and the doppelganger on Earth Minor dies as well.
However the process is not reversed. If a Minor dies, his or her counterpart on Major continues. Scientists on Earth Minor develop a system of contacting Earth Major....and of course, the next step...trying to stop it.
Earth Minor sends a representative over via a lightwave transfer so that he can find his link. Trevor finds his "doppelganger" on this planet, Darrin Talbot. Talbot is one of the top scientists and is also involved in the investigation of the cross-linking of the two planets. Trevor was a simple custodian worker on his planet but must try to explain what is occurring.
As Darrin investigates, he finds out that Trevor is indeed, telling the truth. But unknown to the two of them, Earth Minor has discovered they cannot stop the link, but they may have found a way to reverse it.
It is a battle of lives at stake as two planes struggle in changing the roles...and the lifelines...of the two mirror worlds.
When Trevor realizes the truth, he now knows he must stop Darrin’s shutting down the lifelines and to do that, he must make the ultimate sacrifice.
