“Resurrection” is episode nineteen of season seven of Stargate SG-1.
Daniel, Sam and Teal’c – O’Neill is still recuperating after the events of “Heroes: Part 2” which resulted in the death of Dr Frasier (not quite the death of a major character that becomes more common in recent years, when even being a major character is no guarantee of survival, but getting up there, being the death of an important secondary character); he survived the staff weapon blast due to the improved body armour – are called in by Agent Barrett (Peter Flemming) of the NID, who was first encountered in “Smoke & Mirrors”. A rogue NID cell has been discovered at an abandoned warehouse after someone there called in the emergency services. There are over 30 bodies, and just two survivors – one of the scientists and a girl who apparently killed everyone else. The scientist, Keffler, is less than cooperative despite everything, and isn’t a very nice person.
The girl, Anna, does not remember what happened. There are also many artefacts related to Sekhmet in the facility, and Anna is a clone made from both human and Goa’uld DNA. Although she is not possessed by an actual symbiote, she still appears to be Sekhmet also. And there’s a bomb going to go off. No pressure.
