Present day human John Crichton is unexpectedly sucked through a wormhole and flung to "...some distant part of the universe on a ship, a living ship, full of strange alien life forms." 

Moya hides on a planet to suppress a Peacekeeper beacon. While searching for a painkiller for Moya, John becomes the accidental "first contact" for the inhabitants of the planet. 

Moya is invaded by spawning space bugs, which produce clones of the crew. To complicate matters, a Peacekeeper retrieval squad arrives and Aeryn begins to suffer heat delirium. 

Rygel's ploy to appear regal backfires when he, along with a much needed part of Moya's propulsion system, are snatched by Tavlecs who possess drug-dispensing power gauntlets. 

When two rescued Ilanic scientists come aboard, Crichton finds himself experiencing disastrous future timelines, while D'Argo becomes infatuated with the female Ilanic. 

D'Argo, after threatening the crew with Luxan hyper-rage, is later found docile and happy on a planet and decides to stay. Crichton discovers that the planet's food contains a drug, with the help of a small band of rebels immune to its effects. 

The hulk of the legendary Peacekeeper ship, the Zelbinion, holds a pleasant surprise for Crichton, but Rygel must confront the time spent on the ship where he was tortured by the sadistic commander Captain Durka. 

On a commerce planet, Crichton finds himself lured into an alternate reality controlled by Maldis, a being who feeds off negative energy. He is pitted against Crais in a fight to the death. 

In exchange for samples of the their DNA, a genetic scientist offers the Moyans star charts to reach their respective homeworlds. 

While inpecting access shaft D'Argo is flushed into space. The DRD's turn on the crew and Moya cuts off life support, while the crew attempt to find the cause from a revived but delusional D'Argo. 

After creating a wormhole Crichton's module is repaired on a nearby planet, while Vorcarian Blood Trackers attempt to collect the Peacekeeper bounty placed on their heads. 

Zhaan is asked to help an outpost of fellow Delvians attempting to avoid the madness that threatens them. 

John's flying lessons with Aeryn come to an abrupt end when he is caught in a net left by Zenetian pirates to trap ships. D'Argo must choose between potentially finding his son and rescuing John and Aeryn 

Seemingly abandoned after crash-landing on a planet, Crichton starts a peaceful life alongside inhabitants once ruled by the Hynerians. He unintentionally becomes involved in a power struggle which puts his life in danger. 

A collision with a Nebari ship brings a Nebari criminal named Chiana to Moya, along with a mentally cleansed Captain Durka much to the surprise of Rygel. 

Returning to Earth through a wormhole, Crichton receives an unfriendly welcome but is reunited with his father. Aeryn, D'Argo and Rygel arrive to rescue Chrichton but receive less than humane treatment. 

Moya performs an emergency starburst that fragments her into four different dimensions. As John attempts to find crewmembers missing in each dimension, an energy creature appears to add more danger to their predicament. 

When a group of Peacekeepers from a damaged Marauder board Moya, the crew pretend to be a Peacekeeper prison vessel. The Peacekeeper's secret cargo presents a serious threat when Rygel and Chiana open the container. 

When an injury Aeryn sustained in A Bug's Life threatens to kill her, Crichton and Chiana travel undercover to a nearby Peacekeeper base to obtain a tissue transplant, and are aided by Gilina. Base leader Scorpius penetrates Crichton's disguise and subjects him to an interrogation device called the Aurora Chair. Chrichton's cellmate is a masked individual named Stark. 

After a partial recovery, Aeryn leads Zhaan and D'Argo to the Gammak Base to rescue Crichton. At the base, Gilina does her best to help Crichton who is being repeatedly subjected to the Aurora Chair by Scorpius and Crais. Elsewhere, Chiana and Rygel have problems of their own when the pregnant Moya goes into labor. 

While on the run from the Peacekeepers, the crew of Moya takes shelter on an asteroid with a breathable atmosphere and covered with flora. They soon discover, however, that the asteroid is not as free of predators as they thought. 

When Rygel decides to sell out the crew of Moya to the Peacekeepers, the crew must come up with a way to escape capture. Their luck changes when Rygel returns along with Crais. They formulate a risky plan to destroy the Gammak Base. 

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, and Crichton decides to remove Crais from control of Talyn, Scorpius finally sees his chance to strike. 

D'Argo takes part in a sacred ritual that helps a dying Luxan, an Orican, to pass on. During the ritual the Orican invokes a ritual of renewal, drawing from she thinks is D'Argo's strength. Consequently Moya starts to age rapidly. 

Chiana leaves Moya and takes residence on a planet populated by a young group of aliens who take part in a dangerous and life-threatening rite. 

The crew returns from a Commerce Planet with a load of crackers and an alien called Traltixx, who promises he can alter Moya's electromagnets to make her untraceable. Crichton is skeptical; it seems too good to be true. As they pass through a constellation of pulsars, an increasing paranoia affects the crew, turning them violently against each other. Crichton must fight against his own paranoid delusions to work out what Traltixx is actually doing—and how to stop him. 

A datacam tape is uncovered showing Aeryn as part of a Peacekeeper firing squad that executed Moya's first pilot. The rest of the crew want answers but Aeryn is reluctant to revisit her past—especially her relationship with Velorek, the man who grafted the current Pilot into Moya's systems. Pilot refuses to communicate with the crew, not wanting to reveal his own complicity in the murky circumstances surrounding his installment as Moya's pilot. 

Chiana is given a picture that predicts the future. It depicts the death of Chiana, followed by the rest of the crew who appear to die one by one in self-fulfilling prophecies. 

Desperately short of food, Chiana leads the crew to a dead boudong where she once worked. Without any currency, they must work for food and supply the deteriorating Zhaan with meat. 

When Zhaan and Crichton are stranded in a transport pod, Zhaan recounts the story of her time with Chiana and Rygel after Family Ties. They landed on a planet where 90% of the population are lawyers, and Zhaan was framed for murder. 

After an attack by the Halosians, the crew of Moya find their minds and bodies switched. They must find a way to get their minds back into their own bodies before the Halosians can power up again and destroy Moya. 

A strange energy ball enters Moya and engulfs John. Crichton emerges, followed by a Neanderthal-like version of himself, another version that appears to be a future evolved human. When communication with the energy ball is established, it states that it will leave without destroying Moya, but one of the Crichtons must be sacrificed for its research. 

To avoid capture by Scorpius Crichton is forced to propose to a Princess— however there are competitors for the throne and a rival working with a Scarran plans to eliminate Chrichton. 

After an assassination attempt Crichton is put into hiding on an orbiting cargo ship, delivering him to Scorpius. Aeryn goes on a hazardous rock-climbing trip with a local suitor. 

After being transformed into a bronze statue Chrichton is beheaded. While Zhaan and Pilot confront one of Moya's creators, Crichton, D'Argo and even Scorpius must rescue Chiana from a Scaran. 

Chiana buys a parasite hunting Vork, which creates chaos on board Moya. After several attacks it is suspected that the Vork itself may be the parasite. 

Crichton wakes up on Earth after crashing Farscape One. He believes it to be an illusion, as in A Human Reaction, and tries to find a way out. As things become increasingly chaotic, he begins to lose his sanity. 

While travelling through a mist Aeryn scouts ahead for several hours, but when she emerges, she has aged 150 cycles. She informs Moya's crew that they have to leave lest they be trapped there forever. When she departs again, Crichton follows her only to get trapped on the planet with her, where he's forced to stay for several decades. Stark returns in this episode. 

After Placavian ship is destroyed by Talyn with Crichton, Aeryn, D'Argo, Zhaan, and Stark on board, they are put on trial by the Placavians. During their testimony, the story of their meeting with Talyn and Crais is told from a number of perspectives.

Stark returns from the dead with a plan to save D'Argo's son and make them all rich in the process albeit through armed robbery. What they don't know is that it is Scorpius' money they are stealing. 

With Jothee in Scorpius' hands, the crew of Moya recruit several former enemies to raid the Shadow Depository. 

The crew of Moya assault the Shadow Depository in hopes of rescuing Crichton, now in the hands of Scorpius. 

The crew takes Moya and Crichton to an ice planet, hoping that both can be treated by a Diagnosan. Chrichton's neural chip has taken control of his mind and body and will stop at nothing to survive, including harming Aeryn. 

A one-hour primer for audiences new to Farscape 

With the chip removed, John's speech is restored using a donor held in stasis near death, raising ethical issues. A Scarran lying in wait is accidentally released and captures John. Aeryn is revived at considerable cost to Zhaan. 

The crew of Moya arrive at a supposedly cursed space station which is unexpectedly hit by a massive energy storm. As they do their best to help rescue survivors, another storm changes course directly toward the station. They soon figure out that someone on the station is controlling the storm, hoping to destroy it and everyone aboard. 

Moya collides and becomes fused with a wormhole research vessel. This episode marks Jool's first appearance. 

When it becomes clear that only one of the two ships must survive, the crews of Moya and the Pathfinder vessel must make a choice. In the end, one of Moya's own must make the ultimate sacrifice. 

Stark's power combines with goggles that look backward in time, which pulls Moya's crew backward in time to the site of a legendary Peacekeeper battle. 

The crew of Moya come across a diseased Leviathan used by the Peacekeepers as a prison for the criminally insane. It has been taken over by an individual who "twins" the humanoid inhabitants of the ship and uses them as a food source.

The crew of Moya take some shore leave in a nightclub where a potent recreational drug is popular. When Jool and Chiana disappear, Crichton and D'Argo make a plan to rescue them. 

The Ancient in the form of Jack Crichton accuses the John aboard Talyn of carelessly giving away his wormhole knowledge, but John suspects that his glider has been copied by Furlow. They return to Dam-Ba-Da where Furlow has been offering to sell what she has to the highest bidder. 

The Ancient helps John construct a device to destroy a Scarran Dreadnought to prevent them from leaving with wormhole technology. Furlow, only motivated by commercial interests, steals the device. John reclaims it but is exposed to a lethal dose of radiation in the process. 

The Crichton aboard Moya is knocked unconscious by a hyper-raged D'Argo, and receives bad advice from himself as he enters a world that is quite... animated.

Moya encounters a band of former Peacekeeper prisoners, one of which is a traitor. Talyn returns, but Aeryn has difficulty accepting the presence of Chricton. 

Crichton's negotiations with the Peacekeepers has an unexpectedly bad complication. Talyn finally snaps. 

Crichton agrees to assist Scorpius, but secretly plans on delaying Scorpius's research. The others make full use of the Peacekeeper hospitality on offer.

Crichton, Chiana, Rygel, and Sikozu head to Arnessk, where they find D'Argo, Jool, and Noranti. The happy reunion, however, isn't about to last when the Peacekeepers are around. 

After escaping Grayza, Crichton helps D'Argo and Sikozu plan an escape from the Peacekeepers before the planet becomes too hostile for any life. 

Thanks to Noranti, the crew and passengers of Lo'La are forced to land on a desolate planet where Rygel finds a cache of valuables owned by a group of criminals. When he's caught in the booty's security system, John Crichton and Ka D'Argo must find a way to get him back before the pirates decide to execute him. 

The crew on Lo'La finally reunite with Moya and Aeryn. The good feelings are short lived when Aeryn reveals that she's dying of heat delirium and that Scorpius is onboard. Things get worse with the arrival of one of Aeryn's old enemies and a new Peacekeeper weapon. 

While the crew is viewing a wormhole, Moya is suddenly hit by a large, toxic space plant. The crew must find a way to kill the plant before it kills Moya. Aeryn tells Chiana a secret about her pregnancy, and asks her to keep it secret. Three guesses about what happens with that.
