Gerry meets an attractive woman at Barrel's and drags Lisa with him to a teacher conference in Atlantic City to find her. Robert and Bobbi's secret fling finally becomes public knowledge, while Trudy and Frank are at odds over his inappropriate phone calls in the staffroom.
Based on Gerry Dee's real-life experiences as a high school teacher before he switched to comedy full-time, MR. D is a story about a charming, under-qualified teacher trying to fake his way through a teaching job, just like he often fakes his way through life. The premise shines the light on teaching from the teacher's point of view, and as it turns out, teachers don't know everything, especially Mr. D - who struggles to keep one step ahead of his students.
