Avalon Pt. 1

S9 E1: With the departure of Gen. Jack O'Neill Stargate Command enters a new era. That said Stargate Command's new commanding officer Gen. Hank Landry and SG-1's new leader Lt. Col. Cameron Mitchell barely have time to settle in -- let alone inaugurate a new era -- before the sudden return of the beautiful thief Vala. Motivated by her insatiable appetite for ill-gotten gain Vala has come bearing a stolen tablet that only Dr. Daniel Jackson can decipher. She is convinced that the tablet holds the secret to an incredible buried treasure while Daniel is convinced that some way somehow she's going to make his life miserable. At Mitchell's request however he consents to a meeting with her. Unfortunately the tablet isn't the only artifact Vala has stolen. She has also brought along some insurance -- two ancient Jaffa bracelets that Teal'c explains were once used to bind prisoners to their guards and thus prevent escape. Before Daniel has a chance to argue Vala clamps one of the bracelets onto his wrist and the other onto her own. After Dr. Lee tries and fails to remove the shackles a resigned Daniel complies with Vala's demand and cracks the tablet's code. His translation leads the pair along with Mitchell and Teal'c into a deep and ancient cavern under Glastonbury Tor in England. With the treasure just out of reach they find themselves trapped. Unless they can solve a series of complicated riddles they will never find the treasure -- and worse they'll never get out alive.
