SG-1 is in the briefing room where General Hammond shows them a recently found element called Trinium, which is a hundred times lighter, yet also stronger than steel. SG-11 found the element on the planet PXY-887 and now they have been sent back to extract some more, but they have failed to return since then. The Stargate activates and disturbs the briefing, so while looking through the control room; the glass breaks due to an arrow made of Trinium which has been shot through the gate. Sadly, O’Neil was hit with it and was put in the infirmary, so it has fell on Carter to lead SG-1 on the upcoming mission. Once on the planet, the team finds an empty camp which was set up by SG-11, but no members in sight. After discovering a totem of sorts, SG-1 gets ambushed and knocked unconscious.
