Ep 4. Insiders

The SG-1 team is dispatched to a planet that has been attacked by the Ori, and they are hoping to find some valuable information about their enemy. They are met by a group of people who claim to be survivors of the attack and are willing to help them. However, things quickly become complicated when the team discovers that the survivors are actually working with the Ori.

The team is forced to work with the survivors in order to gather the information they need, but they quickly realize that they are being manipulated. One member of the team is taken captive, and they are forced to make a difficult decision to save her.

Meanwhile, back on Earth, a member of the IOA is pressing General Landry to allow them to study the Ancient device that SG-1 has brought back from their mission. Landry is hesitant, knowing the dangers of the device, but he eventually agrees to let them study it under certain conditions.

As the episode unfolds, the SG-1 team and the survivors on the planet continue to work together, but tensions are high as they struggle to keep ahead of the Ori. One member of the team begins to suspect that someone in the group is not what they seem, but they are not sure who they can trust.

In the end, the team is able to gather the information they need and escape the planet, but not without casualties. The episode ends with the team back on Earth, realizing that the fight against the Ori is far from over.
