Buzz and XR respond to an emergency distress from Sentilla looking for a downed cargo ship of Hyper Bombs.

One of Zurg's Brain Pods (Number 13) goes AWOL, so Zurg hires the Boba Fett-esque bounty hunter Shiv Katall to track him down; Buzz turns out to've been Shiv all this time, in order to make defectors from Planet Z seem to be dead, when they're really in a witness relocation program; Buzz gets found out, so Commander Nebula has to do the Shiv-thing (...which he USED to do, before Buzz came along...), in order to make Zurg regain trust in the existence of Shiv Katall.

Buzz captures ""Pen-like Activation Device"" for Zurg's HYPER-DEATH RAY in a fairly accidental manner (Buzz thinks that it MUST be important and just LOOKS like a pen...everyone else thinks that it MUST be just a pen and that Buzz LOOKS to be going a little loopy...); Buzz is sent to Rhizome to work out overworking-stress with Tubunch. Zurg goes to Rhizome to get a clear shot at Star Command with his HYPER-DEATH RAY, unaware that Buzz is there. Buzz channels his emotions and uses the Rhizome plant-tech to stop Zurg.

While Buzz is testing out the LGMs latest invention (...some sort of space-scooter...), the LGMs are struck by a need to ""heed the heed"". As if hypnotized, they all commandeer a ship and fly off. While Zurg is attempting to dispatch hornets to defeat Buzz and capture the space-scooter thing, the same thing happens to the Grubs. The Grubs and the LGMs arrive on a distant planet (...Buzz and Zurg catch up in a few minutes...), where a giant, intangible, glowing head named Guzelian the Alien (...a member of the Heed, an advanced race that has transcended physical form...) tells them that they must work to bring peace throughout the galaxy. The Grubs return to Planet Z, the LGMs return to Star Command, and both of them then proceed to dis-assemble any weapons or armaments that they have, in order to issue in this new age of peace. After a charming little ditty written and performed by Mr. Idle, entitled ""Let's Make Peace!"", Buzz grows wary of Guzelian's intentions.
