Death Knell

S7 E16: At the new Alpha Site - the safe-haven planet to which Earth's population can evacuate and where the Tok'ra and Jaffa resistance fighters are based - Jacob/Selmak and his daughter Maj. Carter discuss modifications to a prototype weapon. It was developed by reverse-engineering the technology of the re-animation device developed by the Goa'uld system lord Telchak. Right now the weapon is only 70 percent effective against Anubis' super-drone army. Carter is calibrating a new more effective power pack for it when incredibly a fleet of Goa'uld ships approaches the planet. The location was highly classified yet somehow the Goa'uld still found it. Base commander Col. Riley orders an immediate evacuation to the Beta Site and the self-destruction of the Alpha Site base. After the evacuation 90 people are unaccounted for including Jacob/Selmak Carter and Riley. Col. O'Neill Teal'c Dr. Daniel Jackson and SG-3 search for survivors at the Alpha Site. They find Jacob/Selmak who gives O'Neill the semi-effective prototype weapon which has only a few more shots left. Carter has the upgraded and fully charged power pack but Jacob doesn't know where she is or even if she's still alive. Twelve more survivors are found and brought back to Stargate Command where Gen. Hammond questions the second-in-command Maj. Green. Jacob/Selmak tells Daniel how he and Carter had scrambled to download the weapon design into the Matrix Crystal when a drone broke into the lab. Jacob fired the weapon but in its present configuration it only stunned the drone. He and Carter retreated with the rest of the survivors but the drone followed only the two of them. Jacob/Selmak surmises that the purpose of the attack was to eliminate the weapon its plans and its creators. He thinks that because Carter has the weapon design the drone is still after her. Indeed it is. Back at the Alpha Site Carter badly bruised and exhausted has been evading the deadly super-predator all this time. O'Neill and Teal'c are now following her trail and Gen. Hammond has sent an armed UAV (Unmanned Aerial Vehicle) reconnaissance mini-plane to search for more survivors and attack the super-soldier if necessary.
