It's been 3 years since the events of the first "Naked Gun". Frank Drebin (Leslie Nielsen) is still investigating cases in his own special way, but he and former girlfriend Jane Spencer (Priscilla Presley) have broken up. Spencer is now dating a big business man named Quentin Hapsburg (Robert Goulet), who is looking to eliminate a doctor who advocates solar energy. Now it's up to Drebin to save the day once more.
