Farscape

D'Argo and Stark try to heal John, left with his head open on an operating table, while Scorpius attempts to avoid discovery. Zhaan makes a great personal sacrifice, while Jothee and Chiana commit an indiscretion.

Eager to spend the currency aquired from the heist of the Shadow Depository, the crew of Moya head to a Commerce Station. The situation becomes disastrous when the station is damaged by a violent storm, Moya becoming ensnared in the docking cables. As it becomes clear that the storms are not natural phenomena, and the crew looks to escape, D'Argo learns that Chiana has betrayed him with his son.

Moya approaches a wormhole, gets pulled in and fused to another ship.

The crew work 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.

Stark accidentally sends himself, Crichton, Aeryn. D'Argo and Jool back in time where they alter the timeline and 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.

Crichton has been duplicated into two identical Crichtons. Moya's crew, trying to buy a healing agent for the injured gunship Talyn, becomes embroiled in a planet's deadly politics. Meanwhile, Aeryn discovers that her own mother, Xhalax Sun, is leading the Peacekeeper Retrieval Squad sent to recapture Talyn.

Talyn is swallowed by a boodong, leaving Stark and Rygel stranded in a transport pod.

The crew of Moya start blacking out and missing portions of time. Pilot becomes inhabited by another entity who needs to 'taste' each crew member 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.

Scorpius puts the neural chip into his own brain in an attempt to retrieve vital wormhole equations from Crichton.

Talyn gets the urge to fly into a sun. While in its vicinity Stark is contacted by an alien woman who is being held against her will.

Crichton, D'Argo, Jool and Chiana are forced to take a holiday by Pilot as he is fed up with their constant bickering.

An Ancient - again taking the form of Crichton's father Jack - appears on Talyn and accuses Crichton of sharing wormhole stabilising technology with the Charrids, a vicious race who have formed an alliance with the Scarrans. Crichton realizes that Furlow, the mechanic from Dam-Ba-Da depot who once repaired Crichton's module and had a mercenary interest in wormhole technology, is the real guilty party. With a Scarran Dreadnought heading towards Dam-Ba-Da to collect Furlow's data, Jack must unlock the wormhole technology in Crichton's brain in order to build the ultimate weapon - but must first confront the evil Scorpius Clone in Crichton's mind.

After disposing of the Scorpius Clone, the Ancient 'Jack' unlocks the secrets to wormhole technology in Crichton's mind allowing them to build a Displacement Engine, the 'ultimate weapon' that will allow them to destroy the Scarran Dreadnought before it escapes with Furlow's data. Seeing the value of the weapon, Furlow kills Jack and takes off with it. In the ensuing chase, Crichton is fatally exposed to the highly reactive Partanium that fuels the engine. With nothing left to lose, Crichton volunteers to launch the weapon at the Dreadnought, experiencing first hand the terrifying power of the wormhole technology.

A fight between D'Argo and Crichton over the malfunction of D'Argo's mysterious new ship ends with Crichton being knocked unconscious. The Scorpius Clone in Crichton's mind tries to convince John that revenge against D'Argo is the only way to settle the conflict, but John prefers to resolve it in his own head, acting out a Crichton vs. D'Argo cartoon battle set in Road-Runner land. Meanwhile, the ship malfunction leads to the activation of a self-destruct sequence that threatens to blow Moya to pieces should D'Argo fail to deactivate it.

Aeryn is devastated. She leaves Talyn, and grieves on a planet. Talyn's crew tries to help but she doesn't want their help. She spots someone who might be her father. But not all family reunions are joyous.

A group of escaped prisoners come aboard Moya 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.

The crew must stop Scorpius's research on wormhole technology. The only way to stop him is to board the command carrier and figure a way to destroy it from within.

On the Command Carrier, Crichton is making incredible breakthroughs in his wormhole research, accessing information previously locked away. His crewmates are not so sure about the success of the plan, and are debating whether to leave or stay. Crais also has his own interests at heart, and when he is denied access to Talyn by the Peackeepers, he realizes he needs a bargaining chip. He goes to Scorpius and reveals Crichton's true intentions: to sabotage the wormhole research and destroy the Carrier. The plan blown, Moya's crew is immediately arrested, and it seems all is lost.

Moya transports the remains of Talyn to a sacred Leviathan burial ground. Those on board are at a crossroads, each wanting to pursue a separate path. Crichton dreams of returning to Earth with Aeryn at his side, but Aeryn is unsure. Upon entering the graveyard, Moya is attacked by a huge male Leviathan. The crew must team up once more to save their home, but it seems that no matter which way the battle goes, their intertwined fates are sure to unravel.
