As the Goa'ulds splatter against the protective iris installed inside the Stargate the SG-1 team faces several problems close to home. Colonel Jack O'Neill wants to add a new member to the team: Teal'c an alien who risked his own skin to save O'Neill and his team on the other side of the Stargate. But General Hammond won't approve the appointment and O'Neill must watch as military intelligence treats Teal'c like a guinea pig. To make matters worse Kawalsky O'Neill's right-hand man has been having terrible headaches caused by an alien larvae that has attached itself to his brain. What they haven't discovered is that this larvae is trying to take over Kawalsky's body in an attempt to go back through the Stargate. With guidance from Teal'c the doctors operate to remove the alien but did they get it in time? Or is Kawalsky still under alien control ready to kill when the order comes?

O'Neill and the SG-1 team head through the Stargate to a planet known as P3X797 and discover a world divided between a dark and light side with a population similarly split between the Touched and the Untouched. The Untouched who live on the bright side are humans a Bronze Age people who seem almost like the Minoan civilization of Earth. The Touched who live on the dark side are heavy-browed primitives with limited skills and the brutal instincts of animals. The findings would only be of academic interest but when the SG-1 team returns all but Teal'c and Jackson begin a startling transformation: they develop the heavy brows and act with the animal brutality of the Touched. Worse so do many others at Stargate's mountain headquarters including General Hammond. As order breaks down and the project is jeopardized Jackson and Teal'c head back through the Stargate in an attempt to discover the reason for this mysterious transformation. Is this a disease that can be cured or are O'Neill the General and the others all doomed to live out the rest of their lives in the Stone Age?

The SG-1 team returns from the planet Oannes in a panic - and without Daniel Jackson who was last seen being consumed by a column of flames. But as his comrades mourn him on Earth Daniel is a captive of an amphibious-humanoid creature known as Nem who is seeking information about his partner Omoroca who lived on Earth 4 000 years earlier. Daniel struggles to recall his Babylonian history and agrees to have his brain read by Nem's advanced and possibly deadly technology. Daniel discovers common ground with Nem - both have lost their true loves to the murderous Goa'uld - and the key to his freedom. Back on Earth the SG-1 team struggle with the strange feeling that Daniel isn't really dead. The team members use hypnosis to revisit the events leading up to Daniel's disappearance.

Daniel and Vala have been saved from the fanatical Ori followers but -- because their savior is an Ori priest and they're still trapped in borrowed bodies in a distant galaxy -- they're not exactly home-free. Instead the priest transports them to the Ori's holy realm of Celestis where Daniel begins to uncover the secrets of the mysterious gods. What he learns is not reassuring. The Ori seem to be Ascended beings who believe that they deserve unquestioning worship and devotion from all humans. They also consider the more benevolent teachings of their Ascended rivals the Ancients to be evil. For millennia the Ancients have protected the humans of the Milky Way from domination by the Ori but Daniel's activation of the communications device has alerted the Ori to the vast numbers of unbelievers in Earth's home galaxy. As a result the Ori have begun to send out missionaries called Priors. Armed with the power of their Ascended masters and convinced that heathen lives are worthless the Priors' goal is to convert the entire galaxy to the worship of the Ori - by any means necessary. As Daniel realizes that Earth is about to find itself on the wrong end of an intergalactic crusade word reaches Stargate Command that a mysterious evangelist has arrived on a planet formerly occupied by the Goa'uld. Hoping to prevent the recently enslaved humans there from falling prey to what sounds suspiciously like another false god Mitchell sets off to investigate. Teal'c stays at SGC where he and Landry are deep in treaty negotiations with Gerak the power-hungry new Jaffa leader. Mitchell soon returns with an Ori Prior who zealously preaches about the wondrous powers of the Ori to anyone who wants to listen -- and to anyone who doesn't for that matter. Meanwhile after Daniel refuses to worship the Ori he and Vala are returned to the village where they are to be the bait in a deadly trap to catch other heretics. After that they are to be burned to death -- with no interruptions this time. When their bodies still at Stargate Command go into cardiac arrest it's up to Mitchell and Teal'c to find a way to bring them home.

Summoned by the Asgard SG-1 lead by General Landry (Beau Bridges) aboard the Odyssey learn the Asgard have only a short time left to live. Their final attempt to solve their physiological degeneration resulted in each of them developing a rapidly progressing disease leaving them only weeks to live. Fearing their knowledge might fall into the wrong hands they plan to end their lives after handing over their entire knowledge base technology and history to SG-1. But before all the final advancements can be installed on the Odyssey the Ori drop out of hyperspace and engage the ship. As the Odyssey retreats pursued by one of the Ori ships the Asgard destroy their planet taking the other two Ori ships with them. The Odyssey with shields nearly failing is forced to test their new Asgard weapons and is barely able to destroy the Ori ship in time. The Ori able to constantly track the Odyssey before it has time to repair damage send ship after ship trying to destroy it. The ability to track the Odyssey seems caused by the Asgard technology integrated into its core systems. The team is caught in a conundrum that the very tools that seemed to promise their victory over the Ori might actually spell their defeat. Beaming the rest of the crew to a safe planet SG-1 tries to find a way disengage the Asgard technology but are drawn into a fire fight before they have the chance to finish. With shield failed and a final blast just off its hull Lt. Col. Carter (Amanda Tapping) is able to trap the ship inside a time dilation field slowing the blast to appear it's nearly frozen moving only inches a year. With a seemingly inexhaustible amount of time Carter sets at solving their dilemma or else the team will be forced to live out the rest of their days in the dilation field aboard the Odyssey.
