Having been born in the 28th century, Mike Kepler never believed in the existence of Heaven or Hell. The myths of the old faiths had been abandoned and replaced with the teachings of The Church many centuries earlier. The young physicist is shocked to learn that there is an afterlife when he is recruited by the Taipei Corporation. It was created by a team of scientists rather than God. Mike's job is to travel to the past and save people at the time of their deaths using advanced medical technology. The individuals are then brought back to the 28th century, judged on the sins they committed and sentenced to an eternity in the artificial Heaven or Hell. Mike quickly learns that the project is far less noble than it appears. He discovers that many of the people sentenced to eternal torment in Hell do not deserve their fate. When a hero he extracted from the past is convicted simply for being gay, Nick decides to fight back against the Taipei Corporation.
