Stargate SG1 Season 3 Episode 17 A Hundred Days

After SG-1 goes to a planet with a Stargate and meets its inhabitants, Colonel O'Neill is accidentally left behind. The planet will remain connected to their Stargate for only a brief period, and O'Neill is forced to find a way to survive until help can arrive. With no way to contact his team back on Earth, O'Neill struggles to keep alive on this remote planet for a hundred days. After weeks of unsuccessfully trying to make contact with Earth, O'Neill resigns himself to his fate, building himself a home and farming the land. But when SG-1 finally returns to the planet, they find more than they bargained for in their reunion with O'Neill.
