Her affluent, protective parents aren’t so sure she’s ready to make it on her own, but they eventually agree to enroll Carla in a vocational college, where she soon meets Danny (Giovanni Ribisi), a similarly handicapped student with a passion for marching bands. A sweetly awkward courtship follows and, with help from “The Joy of Sex,” the couple negotiate the intricacies of physical love.
