Where No Fan Has Gone Before - Plot

Plot

Zapp Brannigan holds a court-martial of Bender, Leela, Fry, and most of the cast of Star Trek: The Original Series, for traveling to the forbidden planet Omega 3. He orders the group to recount the events that led to the court-martial.

Fry explains that he had learned that Star Trek is forbidden in the future; after the show became a worldwide religion, all of its fans were killed during the Star Trek Wars and the "sacred" tapes of its 79 episodes and six movies sent to a forbidden planet. Leonard Nimoy's head at the Head Museum denies knowledge of the show, but realizes he cannot escape the truth and recounts to Fry how the rest of the cast left Earth.

Fry, Leela, Bender and Nimoy's head journey to the forbidden planet. There they find several original sets from Star Trek, and most of the original cast (a character named Welshy replaced James Doohan, the actor who portrayed Scotty, as the latter "had trouble yodelling" in a musical reunion in the 23rd century) with their bodies and eternal youth. An energy being named Melllvar appears and explains that he became an obsessed Star Trek fan after watching the tapes over and over again. Melllvar gives Nimoy a body, and orders the actors and the Planet Express crew to participate in a Star Trek convention until the end of time. Welshy is killed in a show of force to force their obedience. While Melllvar forces the cast to perform his fan script, Bender, Leela and Fry escape in the Planet Express Ship. Fry convinces the crew to attack Melllvar to save the actors, but Melllvar destroys the ship's engine as he drags it back to the planet.

After seeing the Planet Express crew's attempt to defeat him Melllvar wonders if they are more worthy of his adoration than the Star Trek cast, and decides to settle the question with a battle to the death. After several minutes of fighting (with the exception of Leela and Shatner, who end up making out), Melllvar's mother appears and makes him come home for dinner. While he is gone, the two groups combine the engine of the cast's ship with the hull of the Planet Express Ship to escape. In order to lose enough weight to lift off, the cast jettison their bodies. Melllvar follows the crew into space with his own ship, a Klingon Bird-of-Prey. Brannigan boards the Planet Express Ship and starts the court-martial. Leela points out that while the court-martial is in progress Melllvar is still chasing them.

Fry convinces Melllvar that he cannot spend his life watching Star Trek, and Melllvar agrees to end the chase and "move out of parents' basement." The crew returns with the tapes to Earth. The cast goes with them, deciding that immortality is not worth living with "one really annoying Star Trek fan."
