Prisoners (S02E03)

While exploring a seemingly insignificant planet, Col. Jack O'Neill and the SG-1 team are approached by a ragged figure who pleads for their help from a pursuer named Taldor. They try to defend the man, only to discover that he is a fleeing murderer. "Taldor" means "justice," and, by aiding the man, the SG-1 crew have unwittingly become complicit in his crime. Despite their protestations of innocence, the team is sent through a stargate to Hadante, a penal world where brute strength and raw power rule. Strangely, the most powerful person on Hadante seems to be Linea, a diminutive woman whose mysterious powers strike fear into brutes, such as Vindoor. SG-1 strikes a deal with Linea: If she will help power the stargate using her cold-fusion power source, they will help her escape with them. It seems a fair trade — but there's more to Linea than meets the eye. (Metro-Goldwyn-Mayer (MGM))
