The Tomb (S05E08)

When SG-1 explores the entrance of an ancient step pyramid on a remote world, they are surprised to discover a package of Russian cigarettes. Upon returning to the SGC, they learn that a rogue group of Russian Army Intelligence had traveled to this world and never returned: a trip the Russians had never previously disclosed. General Hammond permits a second Russian team to accompany SG-1 back to the planet on a joint rescue mission to find the missing team. O'Neill immediately finds himself in conflict with their leader Colonel Zukhov, who's not used to taking orders from the U.S. Air Force. Once inside the pyramid, SG-1 and the Russian team become trapped together in what they find is the tomb of an ancient Goa'uld ruler. Even worse, the remains of the missing Russians are found, with evidence that they were killed by some kind of alien creature. SG-1 must find a way to work with the Russian team to deal with this creature and somehow escape from the darkness of the tomb. (Metro-Goldwyn-Mayer (MGM))
