Demons

The SG-1 travels to a planet where the inhabitants are Catholic and live in the correspondent Middle Ages on Earth. They meet the woman Mary ready to be sacrificed because she has chicken pox and her husband explains that demons that come from the Stargate periodically collect human sacrifices to Satan. However, Jack realizes that the demons are Unas indeed and Satan is Sokar that needs new hosts. The SG-1 unsuccessfully try to convince the locals that they could fight and kill the Unas, but their leader tells that they are demons and subdue them using a powerful ring. Now the SG-1 joins Mary and they are chained for the sacrifice. How will they escape?

"Demons" is another good episode of Stargate that uses the Dark Ages to show a people that might have come from Earth but still live in this period of history. The film is highly entertaining and well resolved, despite the weapons and gears of the SG-1 be left behind what was absolutely forbidden in "Star Trek". My vote is eight.

Title (Brazil): "Demons"
