Penny's father is a newspaper owner being sued for libel in his home base of New York. He sends her on a western ski vacation in order to avoid the legalities, but she manages to gain entrance to a room with a mysterious Green Door, an entrance to an illegal fur importation racket from Canada. The culprits turn out to be those pursuing the libel situation back east. She is threatened with possible death, but not only solves the fur racket but winds up scooping a rival reporter. In addition, she gains friendship with a young girl kept in seclusion by a father battling ski facility entrepreneurs seeking control of a broad-ranging lease. They turn out to be the libel claimant villains from back east and wind up with enforced legal charges.
