Synopsis by Hal Erickson
The SG-1 team heads to Cimmerica, in hopes of enlisting the aid of the legendary Norse Gods in their battle against the Goa'ulds. Because team member Teal'c (Chrsitopher Judge), like all Jaffa men, carries a larval Goa'uld within him, he is prohibited from entering Cimmerica and trapped in a beam of light. When O'Neill (Richard Dean Anderson) attempts to release Teal'c, both men are whisked underground to the labyrinthine home of Unas (Vincent Hammond), the original Goa'uld host body. Unas' subterranean prison has been designed to protect his civilization from the Goa'ulds, and as such is all but inescapable. SG-1 team members Jackson (Michael Shanks) and Carter (Amanda Tapping) must rely upon another former Goa'uld host named Kendra (Galyn Gorg) to save their comrades.
