ZIM, Dib, GIR and Gaz appear on Dib's favorite show, Mysterious Mysteries / ZIM tries to destroy the Earth by blowing up Prof. Membrane's power generator. Dib must save the Earth with the help from his future self, or so it would seem.
ZIM is abducted by some very stupid aliens who mistake him for human / Dib tries to catch the mythical Chickenfoot and expose him as a fraud, in order to rehabilitate the field of paranormal investigations.
After aliens visit him at night and grant him extraordinary powers, Dib figures he may finally be able to capture and expose Zim. After destroying their latest mission/plan, Zim sets GIR's controls to a dangerously-high level of loyalty. GIR is now more loyal to their mission... but soon deems Zim to be a threat that must be eliminated.
