One day, Officer Buckle is assigned to take a police dog named Gloria to the school for a safety speech.

During the speech, Gloria, behind Officer Buckle's back, demonstrates the safety tips discussed by acting out the effects in pantomime.

As time passes, Officer Buckle gains fame as he gives safety speeches to other schools with Gloria.

Officer Buckle does not realize the truth behind his fame until seeing one of his taped speeches at a college on the news, revealing Gloria's antics.

Without Officer Buckle, Gloria becomes lonely and falls asleep, ending her stay early; afterwards, a large accident happens at the school as a spilled jar of banana pudding causes students to slip into the principal, who accidentally hurls a hammer towards the crowd upon impact.
