Daniel Jackson discovers that the Stargate was activated in 1945 and a young professor went through, never to return. Together with his still living fiancée, the SG1 team discover the now aged professor, naked and trapped in a decaying fortress, containing the secrets of an Ancient alliance. Will they be able to rescue him and escape to earth in time? Written by Anonymous
The Stargate Command (SGC) receives classified information from the Pentagon and Daniel learns that the Stargate was manually activated in 1945. Further, Professor Ernest Littlefield crossed the Stargate and has gone missing. The SG-1 and Ernest's fiancée Catherine convince General Hammond to let them go to the same coordinates to seek out Ernest. They find him alive and alone in a decayed castle and he shows to Daniel information from four alien races about the Universe. However the castle is collapsing under a storm and the Stargate is not working, and Sam and Teal'c need to get power to activate the Stargate.
"The Torment of Tantalus" is an interesting episode of Stargate SG-1, with parallel stories in different times. I question whether a person would be sane after living fifty years alone in a desert place. My vote is eight.
