After coming to the aid of a crippled alien vessel, Captain Archer brings the ship's crew onboard Enterprise for medical attention. Their leader, D'Jamat explains that the Triannons are a deeply religious people and regard the Delphic Expanse as the "Chosen Realm" and the mysterious spheres are sacred objects created by god-like beings known as the "Makers." The Triannons hijack the Enterprise and plan to use it as a weapon against the enemies of their faith.

• Enterprise discovers a third sphere, and T'Pol determines there are 59 of them.
  
• The Triannons believe that the "Makers" built the spheres to transform the "chosen realm" (the Delphic Expanse) into paradise. They refer to the spacial anomalies as "the maker's breath".
  
• Another crewman is killed when one of the Triannons detonates an organic explosive in his bloodstream.
  
• D'Jamat plans to take Enterprise to the Triannon homeworld to destroy the heretics, who believe the Makers created the spheres in nine days instead of ten. They have been at war for over a century because of this.
  
• When Enterprise reaches the planet, they find it has been completely decimated from the war. There are no major cities left on the planet, and millions are dead.
  
• Hoshi Sato has no speaking lines in this episode.
