John Bourgignon couldn't be happier. In a few weeks, the tubby limousine driver - played by Emmy award-winner John Candy - will walk down the aisle with Nancy Reese (Alley Mills), a bombshell blonde with ties to big money. But Nancy's father, a US congressman and presidential hopeful, can't stand the idea of his daughter getting hitched up to a lowly chauffer. While trying to impress his father-in-law to be (Pat Hingle), happy-go-lucky John finds himself mixed up with the wrong crowd. As his wedding day looms ever closer, the bumbling, lovable driver is confronted with blackmail, brainwash, a murder plot, a jailbreak, a religious cult of aerobics instructors - the list goes on. With a little (not-so-helpful) assistance from his sleazy, film-director friend (Eugene Levy) and limo-driving sidekick (Joe Flaherty), John stumbles his way toward the altar, with plenty of side-splitting laughs to be had along the way.
