The Stargate SG1 season 5 episode 17, titled "Fail Safe," follows the SG1 team as they embark on a mission to save the Earth from destruction. The episode begins with the SG1 team receiving a distress call from the Tok'ra, an underground resistance movement against the Goa'uld who possess advanced technology and are mortal enemies of Earth. The Tok'ra warn the SG1 team that a giant asteroid is heading towards Earth, and if it were to hit the planet, it would cause widespread destruction and potentially wipe out all life on Earth.

The SG1 team reacts quickly and attempts to come up with a plan to save Earth. However, their options are limited, and they realize that there is only one way to destroy the asteroid before it hits Earth. They must activate a deadly weapon known as a "fail-safe" device, which is located on a space station orbiting Earth. The device is designed to destroy any object entering Earth's atmosphere with precision.

The rebels believe that activating the device would mean sacrificing innocent lives, and they are willing to go to any lengths to stop it from being used.

The SG1 team faces a race against time as the asteroid gets closer and closer. They have to come up with a plan to get past the rebels and activate the device before it's too late. However, they soon discover that there are deeper, more treacherous forces at work, and that the rebels may not be the only ones standing in the way of their mission.

As tensions rise, the SG1 team must navigate through a complex web of alliances and betrayal to save Earth from certain destruction. They face tough choices and difficult decisions, and they soon realize that the fate of the entire planet rests in their hands.
