Beast of Burden

"Beast of Burden" is the seventh episode of the fifth season of Stargate SG-1.

Plot
A camera left behind on P3X-888 records the capture of the Unas Chaka, whom Daniel Jackson befriended in "The First Ones". The camera also records the gate address of the planet where the kidnappers took Chaka. SG-1 goes to the address and discover a planet where the Unas are a slave race, declining in vigor due to centuries of inbreeding.

Posing as traders and meeting the villagers and Chaka's captors, SG-1 learn that the Unas had been the masters of the humans when they were controlled by "those with the glowing eyes", aka the Goa'uld and with the tables turned are allegedly better treated as slaves than the humans were. Negotiations break down over price.

SG-1 tries to free Chaka but Colonel O'Neill and Daniel are captured and imprisoned for "beast stealing," a capital offense. Attacking the town, Teal'c and Carter help O'Neill and Daniel to escape, and free Chaka and some of the other Unas in the process. The Unas' human masters attempt to recapture SG-1 and the escaped Unas. Having helped liberate his captured human friends, Chaka kills the man who kidnapped him. Daniel then realizes Chaka thought he was the one helping them escape, as he intended to stay and free the Unas the whole time.
