Abby (Garofalo), a savvy, witty veterinarian who hosts her own radio talk show, is anything but confident when it comes to love. A petite brunette, she describes herself as tall and blonde when Brian (Chaplin), a caller who is smitten with her radio persona, asks her on a date. She then talks her tall, blonde neighbor Noelle (Thurman) into assuming her identity, setting off an escalating series of hilarious and romantic crises.
