9.1 Avalon (Part 1)
General Landry appoints a stunned Lt. Colonel Cameron Mitchell to lead SG-1. Vala, the beautiful thief, has come with a tablet containing the secret to a buried treasure. When they find themselves trapped below the earth, another series of riddles may prevent them from uncovering the treasure... or from getting out alive!

9.2 Avalon (Part 2)
Daniel and Vala have been transported to a village inhabited by worshippers of the mysterious Ori. They find that they have inhabited the bodies of two villagers already under scrutiny for seditious behaviour. Can they convince the villagers of their true identity before the people they inhabit are burned at the stake?

9.3 Origin
Daniel's reactivation of the communications device alerted the Ori to humanity's presence. Now, bent on converting all of humanity to follow its teachings, the Ori have begun sending its missionaries called Priors out to turn non-believers from the "evil" ways of the Ancients... by any means necessary.

9.4 The Ties That Bind
General Landry learns that Congress has plans to severely slash the Stargate programme's budget. Landry calls upon Daniel and Vala to testify about the imminent threat that the Ori pose to humanity. Landry worries what implications this setback will have on the future of Stargate Command.
