Commonly considered a blaxploitation film, the plot centers on Moore's character Tucker Williams, a retired cop who owns and operates a disco and tries to shut down the local angel dust (PCP) dealer after his nephew Bucky (Julius Carry) gets "whacked out" on the drug.

Another PCP user's claim to have served her own baby as Easter dinner constitutes a version of the urban legend known as "The Baby-Roast."

In the audience is his nephew Bucky, a basketball star, who ignores the entreaties of his girlfriend and goes outside to score some angel dust.

Bucky wanders back in, hallucinating, thinking people, or demons, are attacking, and he is taken to the hospital under the care of Dr. Mathis.

He visits the precinct where he used to be a policeman; he is welcomed by cop Kilroy and Lieutenant Hayes, who expresses support for the anti-drug crusade.

Meanwhile, casualties mount: PCP thugs murder Tucker's elderly friend Bob, an expert on Black history.

Tucker's interrogation of one of them, the young man who sold Bucky PCP at the disco, reveals that Stinger is the mastermind.

Then Tucker confronts an even tougher, maniacally-snarling fighter, who bests him and puts him in a gas mask to force him to inhale PCP.

Jason Bailey of Flavorwire opined, "the anti-drug Blaxpoitation epic with cinema’s greatest title, Avenging Disco Godfather ... Tucker pays a visit to either Bucky’s hospital or a scene from Reefer Madness; day players overact wildly as Tucker is told the story of a young, PCP-addicted mother who roasted her baby alive, and other delightful tales.
