The team investigates a ziggurat, some kind of burial pyramid, on a desert planet (P2X-338), when they find proof that a Russian expedition has already been there, probably in search of an artifact called the Eye of Tiamut. After contacting the Russian government, a rescue mission is set up with SG-1 and a Russian team also consisting of 4 members. Primary objective is to find the missing Russian team, and bringing them to safety.
After Daniel deciphers the entrance mechanism, the teams go in, and split up. SG1 finds a skeleton wearing a Russian uniform, and showing little teeth marks all over the skeleton. Some strange creature must have eaten him. Meanwhile the Russian team discovers a Goa'uld sarcophagus, but when investigating against Colonel O'Neil's orders, they set off a trap that seals the entrance of the 4000 year old building, killing one of the Russian soldiers.
Daniel starts translating the text on the walls, while the others start looking for an exit, for possible other members of the Russian crew, and for the creature that killed the Russian soldier
