Dennis is in the frame for a crime he didn't commit, and Mrs Creecher's new super-powered Tech Specs mean she can suddenly see WAY too well: she teams up with Sergeant Slipper to track down "fugitive Dennis" who has to somehow evade the all-seeing Tech Specs so he can prove his innocence and reveal the true criminal.
