The class of nuke 'em high is back, and this time they're in college! Tromaville's nuclear factory has been rebuilt and now includes the Tromaville institute of technology. Located inside the nuclear plant, Tromaville Tech is where Prof. Holt has perfected Sub-humanoids.... Living beings without emotions, who have been genetically programmed to perform menial tasks. When school reporter Roger Smith meets a beautiful subhumanoid named Victoria, they fall in love. It's too bad the creatures have a tendency to go into spontaneous meltdown. Roger is now determined to save Victoria from this messy fate, but first he'll have to face the giant mutant squirrel, Tromie, who attacks Tromaville tech in the explosive climax.
