Titled "Sweet Dreams," the ad is based on the premise that "nobody ever dreamt of driving a midsize sedan . . . until now," and follows a young boy as he experiences a series of magical, dream-like adventures through the streets of San Francisco, along a beach, and through a snow-covered countryside inhabited by unicorns, knights on horseback, and other whimsical creatures. His dream becomes reality, as he drives his all-new Optima through the city streets as an adult.
