John versus wraith worshippers

Team travels to a planet where wraith are secretly worshipped. One of the villagers is the "Queen" and survives by drinking blood. The other villagers join in. The ceremony is held underground. John is led into a trap and is to be the sacrifice. The team finds him in time to keep the villagers from draining him dry. Teyla takes great pride in beating the "Queen". They are cut off by villagers and must fight their way back to Atlantis.

Thanks in advance!
