Demons

Demons is the eighth episode of the third season of Stargate SG-1.

Plot
The SG-1 team arrives on a primitive planet that they soon discover has medieval Christian beliefs. At first, they speculate whether or not a Goa'uld is posing as Jehovah of Christianity. The team enters the village and sees a girl chained up to a pole, they release her and Simon, a monk from the villeage, comes up to them and beg for the girls life. he is told by the team that they are not demons, and the girl is not possesed, she is just sick (she only has chicken pox). and he tells them of this demon that comes to the village, then the Unas enters, and demands that he get 5 people the next day, since no one was there for him to get now. SG-1 realises Sokar plays Satan in this world. The Canon arrives at the village, and is told about the happening. The Canon is the one to choose those to be given to the Unas and blatantly abuses the position. He wears a "magical" ring, that seems to be of Goa'uld technology, that allows him to summon lightning to strike others. Feeling threatened by SG-1, he uses this ring to incapacitate them and rallies the townspeople against them by calling them demons (since they came from the "Circle of Darkness", the local name for the Stargate).

Teal'c is subjected to witchcraft tests on the basis of the mark of Apophis on his forehead ("a mark of the devil") and appears to drown in the last of these tests. Due to his symbiote and meditative state when drowned, Teal'c is able to "return to life", which is deemed to be a sign of Satanic influence. SG-1 is sentenced to be offered to the demon along with Mary, the girl.

The "demon" comes to the village and takes the team and the girl, SG-1 manages to escape from the Unas, and after they recieve their weapons from Simon, they are able to stop the Unas, but not before the Goa'uld takes the Canon as a host. Carter discovers that the Canon has been possessed by the Goa'uld and both host and symbiote are killed. SG-1 then encourages the villagers to bury their gate and they return to Earth.
