Farscape

Continuing work on his theories of wormhole technology, Crichton ekes out an existence on board Elack - an old, dying Leviathan. The peace is shattered by the intrusion of a female alien, Sikozu, and a squad of Grudek mercenaries intent on harvesting Elack's neural tissue. Crichton fights to save his new home, his struggle hindered by the Grudeks' pet: a vicious and deadly alien canine called the Brindz Hound.

Everyone but Aeryn meets on Arnesk, where Jool has discovered the remains of an ancient civilization.

D'Argo and Sikozu come up with a plan to crash Elack onto the Peacekeeper pursuit craft, facilitating their escape. Crichton is forced to consort further with Grayza to ensure success. When the plan goes awry, the crew begins a search for the probe that will reverse the planet's deadly atmospheric conditions, but a most unexpected enemy stops them in their tracks.

The crew is on the way to rendezvous with Moya. After ingesting a concoction of Noranti's they stop for a break on a planet. Rygel is captured and entombed in amber by raiders.

Everyone finally reunites on Moya. But Aeryn returns with Scorpius, who claims to have saved the former Peacekeeper's life.

Crichton correctly predicts a wormhole's appearance near Moya, but simultaneously a giant space plant captures the Leviathan. An attack with D'Argo's ship only succeeds in sending the plant into Moya's conduits, making it even more difficult to kill. Eventually, an agent is found that will repel the plant, but it only exists in Scorpius' cooling rods. In order to save Moya, Crichton will have to place trust in his arch nemesis.

Chiana and Crichton are sucked into a game world ruled over by a virtual Stark, who sends Crichton on a quest to 'Kiss the Princess'. To escape the game, they are forced to battle old friends and enemies in fantastic guises. Meanwhile, aboard Moya, Scorpius escapes and brings the crew under his control.

When Moya is raided by bounty hunters working for the Peacekeepers, every crew member is captured except for Crichton and Noranti. The armoured intruders shrink the captives and imprison them inside holding cavities in their torsos - if Crichton harms them, he endangers his friends as well. Finding that Scorpius is also free and on the run, Crichton teams up with him to fight off the menace, unaware that the leader of the bounty hunters has a hidden agenda.

The crew lands on a planet divided by generations of clan war. After experiencing strange hallucinations, Aeryn is subliminally coerced into assassinating a clan leader. When Crichton also starts having hallucinations, they must uncover the planet's political machinations in order to prevent more killings.

The crew consume food, sharing amongst themselves. Although if not ingested by the same person, it becomes toxic. They must quickly find a cure or they'll die.

Crichton is sucked down a wormhole he correctly senses will appear near Moya. Within "wormhole limbo" he is confronted by an interdimensional being who is intent on discovering why Crichton was entrusted with this knowledge. The alien sends Crichton through various "realities" of past events to illustrate how dangerous it can be if wormhole knowledge is misused.

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

Crichton has arrived home, on Earth. Even though the Moya crew relaxes, on Earth and are treated as VIPs, Crichton can't seem to adjust to life on Earth. After all his adventures, can he still call Earth his home?

Moya takes on a new passenger, Talikaa, when Chiana insists upon it. However Talikaa turns out to be an alien creature in disguise and is intent on harvesting the crew's neural energy.

Scorpius takes Crichton, D'Argo and Rygel into an advanced training camp where students learn mental discipline. D'Argo is confronted with the arrival of Macton, the Peacekeeper who murdered D'Argo's wife, Lo'Laan, then framed him for the crime. When Scorpius forces Crichton into torturous anti-Scarran training, D'Argo must face the demons from his past... alone.

The women of Moya travel to a dead Leviathan to buy a sensor beacon for Moya which will allow her to appear to be a different ship. While there Aeryn and Sikozu spy on a secret meeting between the Peacekeepers and the Scarrans.

Having overheard Ahkna, the Scarran Minister of War, mention the secret Scarran base known as Katratzi, Sikozu is sure this is where the Scarrans intend to take their captive, Aeryn Sun. Though Moya's data banks have no record of Katratzi, Crichton's sure he's heard the word "Katratzi" somewhere before, if only he could remember where. Unable to sleep, Crichton pores over a documentary intercepted from Earth that examines the visit by "aliens" - Moya's crew - and discovers that the documentary just might hold the key to locating Katratzi - and Aeryn.

Crichton and Scorpius travel to one of the 'unrealized realities' where Crichton believes he heard Stark say "Katratzi." Meanwhile on a Scarran ship, Aeryn resists torture.

Moya's crew tracks Aeryn to a Scarran Border Station, where the freighter she is imprisoned upon is about to leave for Katratzi, a Scarran base. To keep the ship docked and under quarantine, Noranti gives Rygel a deadly, contagious disease. Though this gives the crew time to come up with a plan to rescue Aeryn, they do not figure on the cunning and ruthlessness of Aeryn's Scarran captor, Jenek.

Moya arrives at Katratzi. Crichton attends the peace talks between the Scarrans and the Peacekeepers ...with a nuclear bomb.

Scorpius has betrayed the crew. Now they're all captured. Their plan failed, the crew has little choice but to help Scorpius's true agenda.

Now safely back on Moya, Crichton learns of the Scarrans' intention to invade Earth. He feverishly analyzes his wormhole data and comes up with a way to collapse the wormhole to Earth - but the method is not one that he can implement alone. Meanwhile, Braca demands Scorpius be released from Moya and returned safely to his Command Carrier - and Aeryn has a few surprises of her own, including the identity of her baby's father.
