The 209th episode of Stargate SG-1 airs on the Sci-Fi Channel, starring Ben Browder, Amanda Tapping, Christopher Judge, Claudia Black, Beau Bridges, and Michael Shanks. 
SG-1 travels without Carter to a world that Daniel hopes contains a repository of Ancient technology. Instead, they wind up on a world much like 20th century Earth that has not yet made contact with other worlds. Their stargate is in a museum, but they do not have a functioning dialing device. The team plans to wait until SGC makes contact and then request a generator to power the gate and dial home manually. But before that happens, some museumgoers find them; the museum’s security guards assume that SG-1 are political rebels and begin shooting. The museum goes into lockdown, trapping some of the patrons inside Concerned that the authorities will simply kill them if they let everyone go, SG-1 decides to pose as rebels and stall for time. With the assistance of a researcher who has long believed the stargate can connect with other worlds, the team tries to find any relics that might let them power the gate themselves. Unfortunately, once they do, they only manage to make it even more urgent that they power up the gate – because otherwise a naquadah bomb will blow them all sky high.
