Stargate Atlantis Season 2 disk 1 of 5

After Dr. Daniel Jackson managed to find the address of the lost city of the Ancients, the command of the Stargate program was attended by an international expedition for his research led by Dr. Elizabeth Weir. It would seem that it may be easier than to come to the galaxy "Pegasus" and reviving the city of the Ancients? But there has not been without problems: it turns out that in this galaxy, there are also race, capable of destroying both the Earth and other worlds of the Milky Way, and they are called Replicators and Ralphs. It is worth to mention the main enemies of the people in this series. Because, unlike other shows, there is shown a completely terrible and merciless enemy to the people. They are driven by the basic instinct of all living things: they want to eat. But here they are fed by none other than the people and it gives the film an even greater urgency and tension that were not in the previous series.
