In the start of the episode, Guenevere's SARG is contaminated by an alien's punch; while the team was returning to base, her SARG broke free from formation and headed towards the Pilgrimage Point. While trying to get Guenevere free of the runaway unit, her SARG attacks Dan and Sue, knocking them out of commission. Because of the imminent threat of reaching the Pilgrimage Point, UN fighters armed with nuclear warheads are dispatched to prevent the rogue SARG from getting there.
