6. Death Ship

The Space Cruiser E-89, crewed by Captain Paul Ross, Lt. Ted Mason, and Lt. Mike Carter, is on a mission to analyze new worlds and discover if they are suitable for colonization. While orbiting a planet, Mason sees a metallic glint in the landscape. He conjects that this might be a sign of alien life, but Captain Ross disagrees. Nevertheless, the Cruiser prepares to land next to the mysterious object.

After landing, the men find that the gleaming comes from the wreck of a ship exactly like their own. Inside the craft, they discover their own lifeless bodies. Mason and Carter go numb with shock. Ross, struggling for an explanation, decides they have bent time in such a way as to get a glimpse of the future. He says to avoid their fate they must refrain from taking off again. Mason and Carter fiercely object to this plan, especially once they find that atmospheric interference prevents their contacting anyone for help, and that the frigid night-time temperatures of the planet will force them to rapidly exhaust the ship's energy reserves on heat. Ross pulls rank to make them comply.

While looking out the viewport, Carter is transported back to a country lane on Earth. There, he encounters people from his past. He runs to the house that his wife and he shared, and finds it empty except for a telegram notifying her that he has died in the line of duty. Carter is wrenched from his vision by Ross; as Carter describes what he has just experienced, he realizes that the people he encountered are dead. Ross insists it was a delusion. The two then find Mason has vanished.

He is having an emotional reunion with his wife and child. When Ross pulls him back, Mason is enraged and wants to be allowed back, maintaining that his encounter with his family was real. From Mason's pocket, Ross pulls a newspaper clipping about the death of Mason's wife and child. The captain then posits a new theory about what is going on: The planet is inhabited by telepathic aliens who are using illusions to keep them from reporting back to Earth, thus averting colonization of their home. Ross says that if they take the E-89 back up to space, that should break the spell.

The men take E-89 back into orbit. Mason and Carter admit that Ross may have been right about the aliens. Ross then insists on landing the craft again to gather foreign samples to bring back to Earth. When they land again, the wreck of their craft is still present. The successive disproving of Ross's theories, combined with an intuitive knowledge of their condition, brings Mason and Carter to the realization that they already crashed and are dead. Their afterlife visits were real, and their current situation is the illusion. Ross refuses to accept this. He rejects his crew's pleas to be allowed to embrace their deaths and be reunited with their loved ones, and says that they will "go over it again and again" until he figures out an alternative explanation.

The scene then resets to the moment where Mason first spotted the E-89's wreckage, the crew doomed to repeat the past several hours of investigation forever.
