Steve Martin is Harris Telemacher, a wacky television weatherman, who thinks his life is perfect, except for an erratic relationship with a style-conscious girlfriend. Then, one bright and smoggy L.A. day, an electronic freeway sign changes his life, when its advice leads him into a frivolous romance with a young and beautiful blonde and, ultimately, to true love with the woman of his dreams. Set against the magic of Los Angeles, it's "like" the most hilariously romantic story you'll ever experience.
