48 Hours (S05E14)

An off-world mishap causes an SGC-bound wormhole to prematurely disengage, apparently trapping Teal'c on another planet. However, when an attempt is made to dial back out, the computers flag an "unidentified error". It doesn't take Carter long to discover the problem. Teal'c is not stranded off-world. He is trapped within the buffer of the gate itself. While Daniel is dispatched to Russia to secure their DHD, Carter works feverishly to save their comrade. But a complication arises in the form of Colonel Frank Simmons who informs the SGC that the government will not allow the gate to remain inactive indefinitely. He gives them a deadline – 48 hours. Ultimately, to save his friend, O'Neill must partner up with an old acquaintance and seek out answers from a remote and dangerous source. (Metro-Goldwyn-Mayer (MGM))
