"The Voyager Conspiracy" is the 129th episode of the science fiction television series Star Trek: Voyager, the ninth episode of the sixth season. It is the only episode whose title features the word "Voyager".
Seven of Nine decides to increase the amount of information she receives from the ship's database by directly assimilating as much of Voyager's data as possible. This allows her to draw conclusions from varied sources of data and find bugs in one of the systems. Meanwhile, the ship encounters an alien who has constructed a catapult capable of throwing a ship several hundred lightyears in a few hours. The crew of Voyager help him repair his array, with hopes that if he makes the trip successfully they can then use it to shorten their trip home.
Seven of Nine downloads the data about the catapult, but she begins to exhibit paranoid behavior. She uses evidence concerning possible spatial-warp technology developments to convince Chakotay that Janeway might be spearheading a Federation presence in the Delta Quadrant. Although skeptical, Chakotay delays the shield modifications necessary for the catapult trip so he can examine the evidence himself.
After another regeneration/assimilation cycle, Seven has a new conclusion. She uses the same evidence to convince Janeway that Chakotay might be spearheading a power grab for the Maquis with the same technology.
The two end up comparing stories and they realize Seven is acting irrationally. The Doctor determines that Seven has downloaded more information than she can handle.
Seven then starts suspecting a third conspiracy: that the aim of the last five years was actually to grab a Borg drone, herself. Seven steals the Delta Flyer in order to escape from Voyager. Janeway manages to beam aboard. She convinces Seven that she is ill and she returns to Voyager for treatment.
The crew successfully uses the catapult to travel closer to the alpha quadrant, cutting 3 years off their journey.
