 The team arrives in a village where all the people are hiding in a bar. Village elder Goran tells it is not safe to be outside as once about every three months the Daimos sucks the life out of a few people. Ten years ago a ship from the sky crashed and the villagers killed all but one of the monsters inside. Sheppard promises to take care of this Wraith and Ronon is able to track it to a cave. Inside they find a Wraith girl, who runs into the arms of a man, Zaddik. He tells he rescued Ellia ten years ago and has been caring for her ever since. Zaddik has developed a serum that allows her to survive without feeding. Dr. Beckett wants to know all about this serum. He also sees possibilities to perfect a retrovirus that he is working on, turning Wraiths into Humans.
