Armed conflict erupts when aliens from the Fifth Dimension mistake Lieutenant Paris' "Captain Proton" holographic novel for reality. The aliens consider the novel's main character, the evil Dr. Chaotica, to be a threat so they knock the U.S.S. Voyager's controls off-line. Janeway is forced to assume the role of the story's powerful Arachnia, Queen of the Spider People, and infiltrate Chaotica's Fortress of Doom. Meanwhile, The Doctor takes on the role of the novel's President of Earth to help the aliens defeat Chaotica.
