Kay Kyser, his band, and several entertainers begin a tour of overseas U.S. military forces. In Australia, the group is approached by a stranded American teen-ager, Marcy McGuire, who pleads with Kyser for him to take her with them when they leave. Kyser refuses, but this does not deter McGuire, who stows away on the group's plane heading for India. When she is discovered, the American authorities insist she be returned to Australia, but Kyser agrees to take responsibility for her.
