A cranky, atheist philosophy professor loves to shred incoming freshmen of their faith. He is chosen by a group of scientists to create a philosophy for a computer-generated world exactly like ours.
Much to his frustration every model introduced from Darwinism, to Existentialism, to Eastern beliefs fails. The only way to preserve the computer world is to introduce laws from outside their system through a Law Giver. Of course this goes against everything he believes and he hates it. But even this doesn't completely work because the citizens of that world become legalists and completely miss the spirit behind the Law.
The only way to save them is to create a computer character like himself to personally explain it. He does. So now there are two of him—the one in our world and the one in the computer world. (Sound familiar?)
Unfortunately, a rival has introduced a virus into the computer world. Things grow worse until the professor in that computer world sees the only way to save his world is to personally absorb the virus and the penalty for breaking the Law. Of course it's clear to all, including our real world professor, that this act of selfless love has become a complete reenactment of the Gospel. It is the only possible choice to save the computer world and, as he finally understands, our own.
