The SG-1 is searching for an Unmaned Aerial Vehicle (UAV) in a planet but they are captured by a bounty hunter called Aris Boch. He explains that he is working for the System Lord Sokar looking for the Goa'uld Kel'ar, but there is a prize for each SG-1 member. Aris Boch also informs that he hates the Goa'uld, but he is working for them. He offers to the SG-1 to help him to capture Kel'ar; in return, he would let them go. Jack, Daniel, Sam and Teal'c are forced to accept the deal, but soon they discover that Kel'ar is indeed a Korra. Further, he explains that Aris Boch and his people have been addicted by the Goa'uld in roshna, a chemical substance produced by the Goa'uld. What will the SG-1 do?
"Deadman Switch" is an episode with a bounty hunter that is not a bad person. Indeed he is addicted in a chemical substance and needs to work for the Goa'uld. In this episode, the Stargate is never shown, maybe for the first time. The episode is well resolved in the final scene. My vote is seven.
Title (Brazil): "Deadman Switch"
