Plot Summary

SPOILER WARNING OF DOOM: This section or article may contain spoilers!


Zim sees the warning.

GIR is watching a movie he rented from the local mall for the hundredth time. Upon entering the room, Zim expresses his irritation regarding GIR's movie-rewatching habits, but irritation instantly turns to cold fear as the Irken notices the FBI Warning onscreen.


Zim panics and thinks that the FBI is after him. His fears are only exacerbated when his computer makes false assumptions about the FBI being created to fight against aliens, and he gets an untimely call from the mall demanding the video back. Zim takes the DVD away from GIR and breaks into the mall, desperate to return it before the next day, ignoring GIR's protests.

Rankle sees Zim

Rankle spots Zim.

However, this proves easier said than done, since the mall is guarded by an obsessively gung-ho security guard named Sergeant Slab Rankle. Zim makes a run for the DVD return slot, but is captured by the Sergeant's security booby traps, has the DVD confiscated, and subsequently dumped into a holding cell for rule-breakers. With a rousing speech, Zim rallies his fellow inmates to make a bid for escape by climbing on top of each other, forming a human staircase leading up to the chute in the cell's ceiling. Not missing a beat, Zim hops up them and escapes through the hole, leaving the other inmates trapped as they were before.


The mall inmates.

Once free, the Irken dodges the cameras and runs into Rankle's security office. Zim steals back the DVD, and makes a break for the video store, Video Outhouse. Rankle realizes the DVD is missing, and releases his army of zombie soldiers. Zim fears them at first, but when he realizes the zombies are completely brainless, he merely pushes his way through them and deposits the DVD in the return slot.

Rankle is impressed that Zim was able to defeat his zombies, and offers him joint ruling over the mall, but Zim declines and goes home, leaving Rankle alone with his hordes of zombies.

Changes and Cuts
