Season 4 Episode 21 - Double Jeopardy

SG-1 returns to a planet they helped free from Goa'uld enslavement. Once, with the assistance of SG-1, the people of this world were able to rebel against the forces of Heru'ur and win their freedom. Now, they face a vengeful Cronos determined to make them pay for their insolence. SG-1 is prepared to lead them once again, but it turns out their former allies are not so eager to answer the call to arms. After all, they were promised that if they buried their gate, they would be safe. Instead, the Goa'uld returned in ships - and the planet's inhabitants paid a terrible price. O'Neill and his team must win their confidence before they can win the battle against Cronos. Fortunately, they have help in the form of their robot duplicates, eager to assist them on this doubly-difficult mission.
