Dominion

Inspired by Chris Marker's iconic 1962 featurette La Jetée; the year is 2073—a not-so-distant dystopian future—and the setting is New San Francisco, the scorched-earth tech-dominant police state where democracy and personal freedom have been well and truly obliterated.

Strange phenomena surface around the globe. The skies ignite. Terror races through the world's major cities. As these extraordinary events unfold, it becomes increasingly clear that a force of incredible magnitude has arrived. Its mission: total annihilation over the Fourth of July weekend. The last hope to stop the destruction is an unlikely group of people united by fate and unimaginable circumstances.

A parasitic alien soul is injected into the body of Melanie Stryder. Instead of carrying out her race's mission of taking over the Earth, "Wanda" (as she comes to be called) forms a bond with her host and sets out to aid other free humans.

Ba'al travels back in time and prevents the Stargate program from being started. SG-1 must somehow restore history.
