Astronaut John Crichton attempts to use the Earth's atmosphere to propel his module at high speeds. He is hit by a radiation wave and is sucked through a wormhole into a distant part of the universe--straight into the middle of a space battle.

Crichton is sucked down a wormhole and crash lands on a beach...on Earth, Australia. Although the home he has returned to isn't as real as it seems. Everything gets worse when the rest of Moya's crew shows up and are experimented on...killing Rygel.

Crichton and Chiana try to infiltrate a peacekeeper base to get some vital medicine for Aeryn. Crichton gets caught by Scorpius and imprisoned. He is tortured using a device called the 'Aurora Chair' which is able to look inside his mind and where Scorpius learns that Crichton has the secret to creating wormholes.

The Scorpius clone puts John into a dream world to prevent the Scarrans from getting any wormhole knowledge.

Crichton must seek out an old friend who has gained too much knowledge about wormholes.

Jack (The Ancient) unlocks the wormhole knowledge in Crichton's mind so together they can build a device to destroy the Scarran dreadnought.

Moya takes Talyn's remains to the sacred burial ground where D'Argo is forced to destroy a rogue Leviathan that is attacking other ships.

After accidentally returning to Earth, Crichton discovers it he is in 1985 and he has altered the time line, causing his father to be scheduled to fly on the doomed shuttle 'Challenger'.

Moya arrives at Earth in present day, Christmas. The crew show their ships and technology to Earth's scientists. Crichton starts writing a journal. The creature left on board Moya by Grayza manages to get to Earth where it starts killing and hunting down Crichton.

With their Crystherium stores low, the Scarrans must travel to Earth through a wormhole as those flowers grow there. With Pilots help, Crichton tries to collapse the wormhole leading back to Earth.
