Ep 10. The Fourth Horseman: Part 1

SG-1 returns to Earth to find a world on the brink of apocalypse. An ancient plague has been unleashed, infecting all of the people of Earth's closest ally, the Jaffa. When the team discovers that the Goa'uld are behind the outbreak, they must race against time to find a cure and prevent the spread of the disease to other planets.

As they investigate the origin of the plague, SG-1 uncovers a sinister plan by the Goa'uld to unleash the Four Horsemen of the Apocalypse on the galaxy. The team must work with old allies and enemies alike, including the Tok'ra and Ba'al, to stop the Goa'uld from bringing about the end of all life.

As they race against time, SG-1 must also confront their own personal demons. Teal'c must journey to his homeworld to face a harsh truth about his past, while Carter struggles with her romantic feelings for Pete Shanahan. Meanwhile, Daniel Jackson must wrestle with the morality of his actions as a member of SG-1.

But as the clock ticks down and the Horsemen draw closer, SG-1 must unite to save the galaxy from destruction. Will they be able to find a cure for the plague and stop the Goa'uld in time? Or will the Four Horsemen ride forth to bring about the end of all things?
