Dark forces older than time itself are on the attack, hell-bent on stopping the dawn of a wondrous new green age. Don't you hate when that happens? Even more shocking: Bender's in love with a married fembot, and Leela's on the run from the law - Zapp Brannigan's law! Fry is the last hope of the universe, recruited for an ultra-top-secret mission. Could this be the end of the Planet Express crew forever? Say it ain't so, meatbag!
The Planet Express crew must work to fix rips between their universe and another inhabited by a planet-sized, tentacle alien which soon takes over the Earth and uses it's ability to control Fry to command an entire religion which takes over and convinces the inhabitants of Earth to abandon the Earth to live in a pseudo-heaven, leaving the robots of the world to inherit the planet.
