Episode 3 : Upgrades
Anise, a new Tok'ra representative to Earth, approaches Stargate Command for help in testing some mysterious armband devices discovered amid the ruins of a distant planet. Anise believes the devices could be a powerful weapon in their war against the Goa'uld. Because symbiotes seem to render the devices ineffective, she requires human test subjects to prove her theory. Col. Jack O'Neill, Maj. Samantha Carter and Dr. Daniel Jackson volunteer. They are outfitted with armbands and, within a short time, begin to demonstrate incredible strength and speed. Dr. Fraiser becomes concerned, however, when medical tests suggest that the devices might be endangering their lives. Gen. Hammond orders the armbands removed ? only to discover that the devices will not come off. Anise sees an opportunity and suggests that SG-1, now outfitted with the armbands, be sent to destroy a new ship being built by system lord Apophis. The general flatly refuses and orders SG-1 to remain on the base. Unfortunately, Anise isn't taking no for an answer. SG-1, its judgment clouded by the alien devices' influence, defies Hammond's order and sets off on what could be a suicide mission.
Episode 6 : Window of Opportunity
While exploring planet P4X-639, the SG-1 team meets Malikai, a human explorer from another world who shares Dr. Daniel Jackson's interest in an alien computer covered in a strange Latin-like script. As solar flares flash from the red sun overhead, Malikai warns Daniel that the geomagnetic disturbance may be dangerous to the SG-1 team and tells him to leave. When Daniel ignores him, Malikai zaps him with a weapon and begins to program the alien computer. Maj. Samantha Carter and Teal'c rush to Daniel's aid and are caught, with Malikai, in a mysterious blue light. Suddenly, they find themselves back at Stargate Command, ten hours earlier, preparing to head off on the mission from which they've just returned. And then it happens again. And again. And again. As Col. Jack O'Neill returns to eat the same plate of Froot Loops over and over again, he realizes that SG-1 is caught in a time loop and that only he and Teal'c retain their memories through each ten-hour cycle. It's up to them to decode the message on the mysterious machine and figure out a way to break the loop.
Episode 16 : 2010
It's 2010, and a lot has happened in ten years. The Goa'uld have been defeated, and diseases such as cancer have been wiped out. Earth's saviors are an alien race known as the Aschen. Their advanced technology has not only ensured the planet's safety, but it has won them the respect and friendship of all humanity. In spite of vast medical advancements however, Maj. Samantha Carter and her husband, Joe, are unable to conceive a child. The Aschen doctors insist that Carter is fine, but Dr. Fraiser's tests reveal something very different: The Aschen have been lying all along. Carter's investigation reveals an insidious plot to wipe out the human race through a process of slow attrition. Dealing with this insidious alien threat seems virtually impossible. The Aschen have become entrenched in Earth society. They hold all the reins of power. Challenging them would mean certain defeat. Finally, SG-1 comes to realize that there is still hope - ten years in the past.
