As the Goa'uld attack fleet approach Earth, all four members of the SG-1 team are taken prisoner. They get help from an unexpected source when Bra'tac, Teal'c's mentor, reveals that he is on board. Apophis has delayed the attack until his son Klorel is revived, giving them some time to prepare. SG-1 has used all of the C4 on one of the two ships but must find a way to dispose of the second. Back at Stargate Command, Lt. Col. Bert Samuels arrives as a Pentagon liaison officer but also reveals a new weapon they have developed. General Hammond is dubious. They begin to transport humans to transport humans to an Alpha site in order to ensure the continuation of mankind. Written by garykmcd
Hammond is sending people to Alpha Site to build a colony there in case of destruction of Earth. Meanwhile the missiles do not penetrate the Goa'uld shields and General Hammond assumes the SGC again. Bra'tac teams up with the SG-1 and they assume the bridge; however Daniel is seriously wounded and asks Jack to be left behind since the group must blow up both spacecrafts. They head Klorel's ship in the direction of Apophis'ship, and they use two small ships to leave the spacecraft. Meanwhile Daniel foes to the sarcophagus to recover his injuries. Will their plan work?
"The Serpent's Lair" is a great conclusion for Season 1. Now it seems that the Apophis has been destroyed and Earth is free of this powerful enemy. In the end, it was not a bad day for the SG-1. My vote is nine.
Title (Brazil): "The Serpent's Lair"
