Philip J. Fry learns that the
Star Trek franchise has become forbidden since it became a worldwide religion in the 2200s; all of its fans were killed during the Star Trek Wars and the "sacred" tapes of
every episode of the original series and
its films were incinerated, with the remaining copies sent to a forbidden planet known as Omega 3. Outraged, Fry takes
Leonard Nimoy's head from the Head Museum and convinces
Bender and
Leela to join him in a mission to recover the tapes. On Omega 3, they find several original sets from
Star Trek, and most of the original cast with new bodies and eternal youth. An
energy being named Melllvar explains that he became a
Trekkie after watching the discarded 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, killing Welshie, a
supporting character, to ensure 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 force them to battle to the death. After several minutes of fighting, 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. To lose enough weight to lift off, the cast jettison their bodies. Melllvar follows the crew into space in a
Klingon Bird of Prey.
Zapp Brannigan boards the
Planet Express Ship and holds a
court-martial of the occupants for trespassing on Omega 3. 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, allowing the crew and cast to return to Earth. ==Production==
