*On M4C-862, Carter and Hailey join O'Neill and Teal'c, who have been providing security for a team of scientists at an offworld research base. The peaceful moon appears to have no indigenous threat, and the scientists resent the interference of the military, especially when they encounter an alien life form composed of pure energy. The tiny flying beings appear as small glowing lights and are entirely benign during the first encounter, but after one of them is captured, hundreds more attack the team, a threat made far more dangerous by their ability to pass through solid objects.
