Helios 689

Travelers transfer into a cult preparing for
mass suicide . MacLaren's team, the cult, and many other travelers, including senior engineer Bloom, meet at the antimatter facility. Bloom reveals that the future is not as united as it once was. Dosed with antitoxin, they release a toxic cloud to force a local evacuation. Gleason interrogates Delaney until MacLaren returns her to the facility and explains the nature of travelers. Gleason discovers Delaney's escape and prepares to return to her lab. Using the antimatter to power an x-ray laser , the travelers intend to deflect asteroid Helios 685, saving millions of lives and preventing the environmental catastrophes and devastating wars that led to their dark future. Deflecting Helios has been the Director's main goal, even though it could possibly prevent the travelers' own births in the future. Gleason leads an assault, killing most of the cult travelers and Bloom before she can fire the laser. However, travelers transfer into him and his soldiers, sacrificing themselves to complete the mission. Gleason fires the laser while MacLaren and his team save Delaney from the antimatter explosion on Bloom's orders. MacLaren is unsure of the mission's success, as his team remains in the present.
