Enemy Mine
S7, E7: On P3X-403 the SG-11 archeological team headed by Col. Edwards discovers a Naquadah mine that could yield enough of the rare off-world mineral to build many interstellar battle cruisers and other spacecraft. But when geologist Lt. Ritter disappears after going out to inspect the site Edwards whose team is not trained for search and rescue sends for SG-1 and SG-3. Teal'c and SG-3 search for Ritter while Dr. Daniel Jackson studies relics found by SG-11. Among the artifacts is a large yoke used to harness a race called the Unas which was long ago enslaved and abandoned by the Goa'uld. Daniel believes that Unas may still live on this planet and that they saw Ritter as an intruder in their territory and attacked him. Daniel's suspicions are confirmed when Teal'c and SG-3 find another entrance to the mine near which Ritter's body is hung up like a scarecrow among some Jaffa warriors' skeletons that are similarly displayed. When Edwards hears the news he becomes incensed. Against Daniel's advice he and other SG forces enter the dense forest where Ritter disappeared - and are attacked by a horde of Unas. During the skirmish Col. Jack O'Neill is wounded in the arm and is about to return fire when Daniel cries out in the Unas' primitive language. The aliens retreat and after an angry discourse with Edwards - who does not care for civilian Daniel's involvement - O'Neill takes the matter to Stargate Command. There to Edwards' consternation Gen. Vidrine from the Pentagon authorizes Daniel's plan to negotiate with the Unas with the help of Chaka an Unas who SG-1 encountered on another planet and with whom Daniel has kept in contact. If negotiations are resolved within the time allotted to determine the viability of the mine fine. If not Vidrine authorizes the use of deadly force. With O'Neill laid up in the in the infirmary and Maj. Samantha Carter performing a complete overhaul of the stargate's diagnostic system Daniel accompanied by Teal'c must handle the uncooperative Edwards and the Unas situation on his own.
