Stargate SG-1: Season 9

An Air Force pilot attempts to reassemble SG-1 after they have gone their separate ways. An old "friend" arrives on Earth asking for Daniel's help in finding an ancient treasure -- and she won't take no for an answer.

An Ancient communications device renders Daniel and Vala unconscious, sending their minds to another galaxy -- where they inhabit the bodies of two people persecuted by the followers of an evil religion.

When Daniel and Vala follow a mysterious man to find answers to their questions, they discover the Ori. The Ori, like the Ancients, are ascended beings, but evil and feeling a need to be worshipped. They have no rules to restrict themselves. Unknowingly, Daniel and Vala reveal that life in our galaxy was created by their long forgotten enemies. They begin to send their missionaries, Priors, through the Stargate. The first planet visited by a Prior in the Milky Way is P3X-421 and the SGC pays him

Hoping to disconnect the kor mak bracelets effects keeping them linked ("Avalon"), Daniel, Teal'c, Mitchell, and Vala try to pry the information out of the person she stole them from in the first place. When he wants something in return, they discover that his request isn't so easy to complete, and they must go on a series of quests to please his demands.

In order to steer the planet P8X-412 away from Origin, SG-1 is tricked by Vala into going to the planet she previously ruled as a Goa'uld. The inhabitants of the planet know nothing of the downfall of the parasites, and they believe that Vala is still their goddess, until a prior shows up, and attempts to expose her for who she is.

Samantha Carter returns to the SGC when the Ori seize control of a planet named Kallana as a foothold in the Milky Way Galaxy. After several attempts to halt the process, they discover that they have been helping the Ori achieve their goal, instead of foiling their efforts. The Ori have been building an enormous Stargate to allow their ships to enter the Milky Way, but they are stopped by Vala, who dies in the process, although there is a possibility that she got trapped in the Ori galaxy.

After Ba'al contacts Stargate Command, they learn he has been living on earth for several months as the head of a major corporation. His demands are that he is allowed to live in peace, or he will blow up a naqahdah bomb somewhere in America. Yet Gerak is determined to capture him... and takes a less "subtle" route. The bomb proves impossible to disarm, so Prometheus beams it into space where it detonates harmlessly, but Ba'al escapes with his many clones at his disposal.

A group of legendary Jaffa attacks SG-1 on a planet designated P9G-844 and captures Mitchell. While the rest of the team is forced to retreat, Mitchell is accused of killing one of the Jaffa. As punishment, he must square off against the slain Jaffa's brother, but he could be Mitchell's salvation.

SG-1 finds a man frozen in Ancient stasis on P3X-584, and brings him back to the SGC to find out his story. But when Daniel researches the laboratory where the man was found, he discovers that he was grown by Anubis to be a genetically advanced human.

Earth is infected with a deadly Ori plague, prompting an ally from SG-1's past to come to their aid. Gerak proposes that the Free Jaffa follow the Ori religion.

As the Ori plague spreads rapidly, SG-1 hopes that the Prior who caused the disease may hold the key to its cure. Gerak tries to rally the Jaffa to the Ori's cause, prompting Teal'c and Bra'tac to initiate a resistance.

SG-1 encounters the Galarans, a civilization that flourished under the umbrella of the Asgard Protected Planets Treaty, after centuries of Goa'uld domination. Due to the disengagement of the Asgard from the Milky Way, the Galarans have become concerned for their safety and developed a memory-grafting device, with which they hope to accelerate their technological development. They are eager to trade this technology with Earth in exchange for hyperdrive technology. After Mitchell's first dose of t

More than fifteen SG-1 teams arrive at Stargate Command, one team at a time, leading the 'real' team to conclude that each of the teams have been inadvertently displaced from different parallel realities. One SG-1 team that arrived has Stargate Command's Dr. Janet Fraiser and the Tok'ra leader Martouf as members, both of whom have been dead for two years in the current reality. The events are ultimately revealed to be a plan by the SG-1 team that arrived first to steal Atlantis' ZPM to save thei

Ba'al brainwashes members of the Jaffa High Council to thwart their move towards democracy. Cameron Mitchell faces a tough decision when he learns that an old friend is about to die.

The Rand Protectorate ("Icon") converts to Origin and is rewarded with the design for a powerful satellite weapon, which they threaten to use against the Caledonians. When Prometheus tries to disable the satellite it destroys the ship, although most of the crew escape to Caledonia. They are ultimately able to return to Earth through the planet's Stargate but after doing so, dialogue between Rand and Caledonia breaks down and the two nations annihilate one another.

SG-1 is captured on an alien world after a deal with the Lucian Alliance goes bad ... and the planet's Stargate goes missing. SG-1 is rescued by the new Earth ship Odyssey and they go on a successful mission to retrieve all of the stolen Stargates from Ba'al.

The Ori have engineered a bioweapon of bugs (known as R-75 or "Prior bugs"), asexual, fast-reproducing, omnivorous insects. When given meat, they multiply rapidly and become voracious swarming predators, able to strip a human to the bone in moments. They prefer darkness and hunt via echolocation. When a group of Earth diplomats visit the off-world Gamma Site research base, R-75 overrun the base and consume most of the base personnel. SG-1 must flee to a research site and set up a message to aler

Mitchell and Carter are shifted to another dimension, making them invisible to everyone at the SGC. Teal'c and SG-12 discover that the Sodan have been brutally attacked.

Vala Mal Doran makes contact with Stargate Command from the Ori home galaxy, and tells the story of her life undercover in a village of followers building the Ori's invasion fleet and her mysterious pregnancy. She ultimately joins an anti-Ori resistance movement with plans to destroy the fleet, but the plan fails and Vala is nearly killed by her husband Tomin before she convinces him to spare her and take her with him to war in the Milky Way galaxy.

SG-1 discovers the village of Camelot on PX1-767 and must face Merlin's security system when they go in search of an Ancient weapon. The Ori invasion begins. A fleet composed of ships from all over the Milky Way made up of the Earth ships Odyssey and Korelev along with ships from the Free Jaffa, Tok'ra, Lucian Alliance as well as one Asgard ship, face off against four Ori ships and are decimated. The Korelev is destroyed with Daniel and Mitchell on board. Vala, on another ship, can only watch th
