Stargate Atlantis: Season 3, Episode 4

3 - 4: Sateda

Exploring a village, the team is suddenly attacked and taken prisoner. It turns out that Ronon had visited the planet before, and unknowingly lured the Wraith there. The Wraith then made a pact with the villagers that if they capture Ronon and contact them, the village will be spared from any future culling.
