Odyssey 5

During the surveillance of a suspected Synthetic front, Angela and Kurt engage in a firefight which leaves Kurt in the hospital and Angela abducted by the Synthetics. Following a tip from his old friend and Menthor, Leyton Scott, Chuck learns of a rock, brought back from the moon, that is the link between the Cadre and The Sentients.

Angela is haunted by the apparent ghost of a pilot who disappeared two years ago.

When Taggart wakes up in a hospital with Paige beside him, he begins to believe that the destruction of the world may have been a dream. What he doesn't know is that it is all a ruse by Dr. Bertran, who is trying to stall his activities long enough to download information from his brain.

The Odyssey crew scramble to save the life of Angela's father, Senator Perry, when he's threatened by a terrifying new breed of Synthetic. Paige deals with her emotions after learning the truth about the Odyssey mission.

The residents of a small town and a select group of scientists (including Mendel) are brainwashed into believing "The Lord" has specially chosen them to construct a passageway designed to bring "Him" to Earth. Taggart and Neil must reach Mendel, before it's too late.

Marc faces expulsion from the Astronaut Training program. Paul takes Sarah to court because of her apparently irrational obsession that their son will get cancer. Taggart suffers from the effects of a Sentient-designed virus.

Neil's friends at school are taking a new drug called "Rapture", which appears to boost their intelligence and may even promote telepathy and telekinesis. Neil finds out that his friend Deckard got the formula for the drug from a web site, but in his attempt to get a sample for analysis he is forced to take the drug. Meanwhile, Taggart's new boss Cynthia Hodge suggests that he had something to do with sabotaging the last space mission, but appears to be happy that the mission failure has hastened the day when manned space flights will be replaced by totally robotic ones. A retired astronaut, Leyton Scott, tells Taggart that a group called "the Cadre" have been trying for the last 20 years to get rid of manned space flight. But then Leyton reveals that he is dying from "Moon Sickness", a strange disease that strikes only Apollo astronauts, which may have something to do with their having brought more than just rocks back with them from the Moon. Because of Angela's apparent mental br

When a top prosthetics researcher is found dead, Neil receives an anonymous e-mail telling him that the man was murdered by the "Synthetics" whose existence the Odyssey 5 group has discovered, which it says are the physical manifestations of Dr. Chandra's "Sentients". It claims that they are now after the researcher's six-year-old niece Stevie, all because of a ""cybiotic interface"" he was working on which would allow computer technology to control organic systems. Visitng Stevie's teacher, they find out that she is deaf and received a cochlear implant, which her uncle had been tinkering with. Eventually, the team locates Stevie and finds out that her implant allows her brain to control a swarm of insects that have been fitted with cybiotic interface chips. But mysterious figures who may be Synthetics have relentlessly tracked Stevie to Kurt's place.

NASA's Project Bright-Sky is accelerated due to Ed Scriven's death and, knowing that a next-generation version of the Bright Sky satellite is what Odyssey 5 was launching on the day Earth was destroyed, Taggart determines that he must put his career on the line to sabotage the deployment of the current version. Neil realizes he's falling in love again with his old high school girlfriend, Holly. Sarah and Angela use their knowledge of the future to try to stop the kidnapping and murder of a young girl, which was front-page news in the original timeline, only to find that their actions have changed the future unpredictably. Mendel, determining that an organism comprised of the mysterious artificial tissue would be cold-blooded, assembles a thermal imaging system that will distinguish humans from the "Synthetics".

The crew attempts to go back to their lives of five years prior to the destruction of the Earth, while also trying to begin their investigation.
