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.

A scientist extracts DNA from several of Moya's crew, promising them that with it he would be able to use it to find the location of their home planets. Things get more interesting however when he asks for some of pilot.

While on a transport pod piloting lesson with Aeryn, Crichton gets caught in an energy field which is invisible to their sensors. Back on Moya, a strange guest docks and comes aboard to warn the crew about The Flax, an invisible energy net created to catch ships.

Moya responds to a distress call from another pregnant Leviathan. On arrival at a planet they are contacted by a Delvian who informs them that the distress call was a deception. It was her way a getting Moya to come to them. The Delvians have a hidden agenda though. They want to forcefully take Zhaan's knowledge and learn how she overcame her insanity.

Moya is hiding from a peacekeeper command carrier in an asteroid field. The crew receive a distress call and Crichton, Zhaan and D'Argo go down to one of the asteroids to rescue a women who has an unusual appetite.

Crichton, Aeryn and D'argo are stranded in an asteroid field while Scorpius searches for them. Their safety depends on Crais, who is nearby in Talyn. Aeryn teaches Crais how to control the young Leviathan - the only thing she can offer in return for the lives of her friends. When Moya returns to the asteroid field to look for her offspring, Crichton decides to remove Crais from control of Talyn. Scorpius finally sees his chance to strike.

Maldus returns to torment the crew, convincing them that their friends have perished. One by one, the evil sorcerer drags them into his realm.

Moya arrives at a planet where the population test their genetic compatibility by kissing. Crichton kisses a princess, who is next in line for the throne, and discovers that his DNA is a perfect match for her. He must now marry her and they will rule together.

Princess Katralla's mother brings in Scorpius promising Crichton that if he doesn't marry her daughter, she will hand him over. Meanwhile, Prince Clavor starts a plot to assassinate Crichton so that he may ascend to the throne instead of his sister.

Now married, Crichton and Katalla are frozen into living statues so that they may watch over the presiding governments of the next eighty cycles. Immediately, Clavor and the Scarran emissary attempt another assassination and succeed in removing Crichton's head. The crew must save John and Chiana while escaping Scorpius.

Stark returns to Moya with a plan to rob a shadow depository and buy a contingent of slaves, one of which is D'Argo's son Jothee. D'Argo attempts the robbery on his own however and now the crew must recover him as well as the money they require.

Moya docks at a commerce station so the crew can spend some of the money they acquired from the depository. Disaster strikes however when the station is hit by a storm.

There is an accident while D'Argo is demonstrating what his ship can do. He blames Crichton and knocks him out. In his unconscious state Crichton has some animated dreams.

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.

Crichton, now aboard a dying leviathan named Elack, encounters an alien named Sikozu who aids him in stopping the Grudeks who are intent on obtaining toubray (Leviathan neural cluster tissue).

Crichton falls into a wormhole and meets up with a strange man who shows Crichton the consequences of wormhole travel.

Crichton watches a documentary that Moya receives from Earth about their recent visit showing interviews with Crichton's relatives and other people who interacted with the crew.

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.
