SG-1 heads to the planet PXY887, the source of the valuable element Trinium. The planet is inhabited by the survivors of the Salish, a Native American tribe, who refuse to turn over the Trinium, preferring instead to give the element to the "great spirits" inhabiting the planet. It is up to O'Neill (
Richard Dean Anderson) and his crew to prove that the "spirits" are not what they seem--and that their intentions toward the Salish are anything but noble. ~ Hal Erickson, All Movie Guide
