The Brotherhood

"The Brotherhood" is the sixteenth episode of the first season of Stargate Atlantis.

Plot
According to a rumour, a valuable Zero Point Module is hidden on the planet Dagan. The Stargate team searches for it.

When they arrive at the planet, they learn that there is an ancient group, called "The Brotherhood" that was charged by the Ancients to protect a valuable object and when they (the Ancients) returned, they would reward them for guarding the object. The team suspects this object is indeed the missing ZPM.

Back at Atlantis, Dr. Zelenka has discovered new long range scanners, which can track objects into deep space. It has activated because of a Wraith dart inbound for the planet.

When they finally locate the place where the object is hiding, an old Genii enemy, Kolya appears in the scene to sabotage their plans. They realize that one stone (out of nine) is missing for them to activate the release mechanism.

They get back to a previous location where Rodney finds the missing stone. In the meantime, Sheppard and Teyla had managed to prepare a little bit, so when Kolya and team arrive, they are ready. After a member of Kolya's team dies by placing his hands in the device that would release the ZPM, Rodney and Sheppard realize that the stones need to be arranged on a particular pattern, so that they add up to 15.

On Atlantis, three puddle jumpers have been scrambled. One is destroyed, while the dart begins to scan the city. After completing its mission, it self destructs.

Back on the planet, once the stones are rearranged, they are able to release the ZPM. Taking advantage of Kolya's distraction, Teyla, Sheppard and Ford get control of the situation. Kolya tells Sheppard that the reasonable thing to do was to kill him. Sheppard tells him that it would and if he ever interfered again, he would.

They leave the place with the ZPM, but when they are halfway to the Jumper, a group of locals surround them and they have to give away the ZPM: the woman that had been helping so far was in fact the leader of the Brotherhood. They try to reason with her, but since Rodney had already commented that they were not from Atlantis but from Earth, the locals believe that the Ancients are going to return in the future. Until then, they going to hid the ZPM on another world.

Back at Atlantis, the team updates Elizabeth Weir, who tells them about the dart. Zelenka also reveals that the dart sent its information into deep space to three hive ships, which will arrive at Atlantis in two weeks.
