During her wayward travels, she meets and falls for the head of a swing band, Windy McLean. Although he doesn't reciprocate her feelings at first, she follows the band - hiding in an ocean liner - all the way to New York. Once she arrives, problems arise due to Windy's girlfriend and the immigration authorities.
