Cornfed leaves for a much-needed vacation. While he is away, Duckman becomes mesmerized by a black model/private eye who quickly gets him involved in a world of murder, power, lust and every black exploitation cliché that exists with a side of a Spelling/Goldberg production.

Convicted of fraud, Duckman is sentenced to 5,000 hours of community service. He is sent to a dangerous inner-city high school, located a half a block from his house, where he becomes a substitute teacher and it turns out that his is the most ""Dangerous Mind.""
