 The puddle jumper arrives on a planet that neither Teyla nor Ronon have visited before. They land near an abandoned campfire, only to find themselves under attack by the indigenous people. They are rescued by a flying vehicle that escorts them to a city of the advanced Olesians. Their magistrate tells the stargate is on a prison island, where only the most violent criminals are sent. According to him this has kept the Wraith away from the city for centuries. He tells McKay their scientists have recently found a mineral that is fissionable, but does not produce any radioactivity. McKay is very interested and the magistrate seems willing to trade. While the jumper returns to get Dr. Weir for the negotiations, the prisoners open fire. They manage to shoot it down.
