Farscape

The Diagnosan's assistant, Grunchlk, sets a Scarran loose. Scorpius uses a device to control Grunchlk and plots to escape from the ice planet with John's neural chip.

Moya docks at a commerce station so the crew can spend some of the money they acquired from the depository. There are complications, however, when a storm strikes the station.

Moya approaches a wormhole, gets pulled in, only to collide with another ship and become fused with it. Only one ship can ultimately survive, and the aliens aboard the other ship will stop at nothing to be sure that it will be theirs.

The crew works out a way of getting free from the other ship and out of the wormhole. Things become more complicated when their new 'friends' begin to sabotage Moya and Crichton picks up a transmission from Earth.

While visiting a Peacekeeper memorial, Stark accidentally sends himself, Crichton, D'Argo, Aeryn and Jool back in time where they alter the timeline and then are forced to interfere further to restore it.

In need of supplies, Crichton lands his transport pod on a dying leviathan which is full of hungry cannibals and a scientist who has the ability to create clones.

Moya and Talyn, who is seriously damaged, rendezvous. They hide in the atmosphere of a planet to prevent the Peacekeepers from finding them. D'Argo and Rygel go down to the planet to find some Chromextin, a drug that will help Talyn recover. Meanwhile, Aeryn learns more about her parents and there are two Crichtons on board continuing from the last episode.

Talyn is swallowed by a giant space creature known as a Budong. Crais' neural connection to Talyn malfunctions and Aeryn is forced to take control of Talyn. Meanwhile, Stark and Rygel come up with a way to help Talyn escape from the Budong.

The crew of Moya start blacking out and missing portions of time. Pilot becomes inhabited by another entity who needs to 'taste' each crewmember to determine if they too are being inhabited.

Talyn lands on a planet covered mostly with vegetation that will help him to heal. Crichton, Aeryn and Crais leave the ship in search of Xhalax.

With his wormhole research stalling and his situation desperate, Scorpius inserts the original 'neurochip' into his own brain. He hopes to make contact with the clone of Crichton's personality that spilled in to the chip when it was in Crichton's brain. When they meet, Scorpius realizes that it's not going to be easy to get the clone to share information. Meanwhile, a defecting Peacekeeper scientist offers Crichton the secret of wormhole technology.

When Talyn draws dangerously close to a sun because he is being pulled by some mysterious force, Talyn's crew learn that a creature named Mu-Quillus is responsible. Stark then makes a pact with a spirit of a dead alien woman and puts the whole of Talyn's crew at risk.

While enjoying their holiday away from Moya, Crichton, D'Argo, Jool and Chiana get a little too drunk. The next day when Crichton and D'Argo come to they find that Chiana and Jool are nowhere to be seen, now Crichton and D'Argo must work out what really happened the night before.

When Crichton is accused of sharing wormhole stabilizing technology with a race known as the Charrids by the Ancient who calls himself Jack. Crichton and the rest of Talyn's crew must seek out an old acquaintance who really is the guilty one.

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

There is an accident whilst 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.

Still grieving for Crichton, Aeryn travels to a planet to make contact with someone claiming to be her father. After meeting with him, Aeryn goes in search of a creature who, according to her father, can channel the dead. But where her father is, can her mother be far behind?

A group of escaped prisoners come aboard Moya. They are followed shortly by Aeryn, Crais and Rygel who have finally returned from Talyn.

D'Argo and Rygel meet Braca and Scorpius in a cafe to conduct negotiations when it is unexpectedly attacked.

Crichton and the rest of Moya's crew arrive at the Command Carrier to try and put an end to Scorpius' mad obsession with wormhole research. Slowly Crichton gains Scorpius' trust, but when a Peacekeeper commandant arrives at the Carrier and tells Scorpius that he must put an end to his wormhole research, Scorpius shows Crichton something which he has been searching for over the past three years... Earth.

Crais and Talyn make the ultimate sacrifice to save the crew of Moya, by Starbursting into the Command Carrier causing it to slowly collapse in on itself. Meanwhile Scorpius and Crichton move closer to the wormhole technology they are both looking for.

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.
