Ep 19. Dominion

In Stargate SG1 season 10 episode 19 titled 'Dominion,' the SG-1 team faces their toughest challenge yet as they try to save the galaxy from destruction at the hands of a powerful enemy.

The episode begins with the team finding themselves stranded on a barren planet with no means of escape. With their ship damaged beyond repair and their supplies running low, SG-1 must find a way to contact Earth for help before it's too late.

However, their hopes are quickly dashed when they discover that a rogue Goa'uld named Ba'al has taken over the Stargate program on Earth. With Ba'al in control of the gate, SG-1 is unable to make contact with anyone back home.

As they struggle to survive on the planet, SG-1 comes across a group of Jaffa who are also stranded. The Jaffa are led by Gerak, a former enemy who has now joined forces with SG-1 to stop the threat of the Ori, a powerful race of beings who seek to conquer the galaxy and force all to worship them as gods.

Gerak and his Jaffa are on a mission to stop the Ori from gaining a foothold in the galaxy, and they have a plan that they believe can succeed. But to do so, they need SG-1's help.

Together, SG-1 and the Jaffa team up to take on the Ori and their army of followers. The battle is intense and brutal, with both sides suffering heavy losses. But in the end, it is SG-1's ingenuity and determination that saves the day.

With the Ori defeated, SG-1 returns to Earth to confront Ba'al and reclaim control of the Stargate program. But the victory is bittersweet, as the team mourns the loss of their fallen comrades and the toll that the war has taken on them.

Despite the hardships they have endured, however, SG-1 remains determined to continue their mission of exploring the universe and defending Earth from threats both known and unknown. For them, the fight is far from over.
