Stargate Atlantis (2004) - 5x09 - Tracker

McKay and Ronon, each unaware of the other's motive, volunteer to assist Dr. Jennifer Keller with a medical follow-up away from Atlantis. But once in a settlement, a nervous child patient prompts Keller to ask Ronon and McKay to wait for her in the local tavern while she finishes her treatment. Later, when the pair return, they are surprised to learn that she left sometime ago. An exhaustive search of the village turns up no sign of her. But a set of footprints in the dirt just past the village confirms Ronon's mounting suspicion that Keller has been kidnapped. Ronon, wasting no time, begins to track her abductor while McKay runs back to the stargate to radio for assistance. But just then, four Hunter Wraith come through the gate and fan out. Ronon, knowing full well that these Wraith exist to chase Runners, suspects there is a connection to Dr. Keller's disappearance. And he knows he must draw on his uncommon skills as a former Runner if he is to save her.
