An alternate planet, Plagathon, which is a planet quite similar to Earth, with only minor differences, has been discovered in the sixth dimension. The American NSA or National Security Agency has found the portal that opens up to the alternate planet. People can traverse back and forth under strict requirements. Earth people mingle easily on Plagathon, but the reverse doesn't seem to work very well. It is on one of these times that a woman from Plagathon opens a portal, that things go wrong. It is the first time that the computer has ever made a mistake. This mistake is very deadly to an Earth man named Paul Price and particularly to his family. Paul is thrust into a situation that he is ill-equipped to handle, however his best turns out to be more than anyone bargained for. Paul teams up with an unlikely person, his ex-wife, and they proceed to square up the injustice that has fallen upon them.
