Okay, okay. The plot in The Naked Gun is about assassinating the queen of England. But if you squint, the queen of England is kind of like a president, right? So long as you ignore the prime minister? Just go with it. President Queen Elizabeth she is.
Ricardo Montalban intends to murder President Queen Elizabeth with the aid of his sleeper agent, California Angels right fielder Reggie Jackson. Luckily, hot cop Frank Drebin is able to foil this plan by squashing squashing Jackson with a tranquilized fat woman. Whether he meant to do that or not will forever remain up for debate. But President Queen Elizabeth is safe. That's the important part.
