Partners "Smilin' Bob" Corey and Jim O'Neil are forest rangers sent to peacefully "penetrate" Paradise Valley, which is scheduled to become part of a national park. Although the townspeople are sullen about their presence, they manage to befriend Marie Roselli, an Italian girl whose brother Wolf owns a cattle ranch and from they obtain supplies. Before they; know it, Bob and Jim get caught up in a kidnapping, an illegal logging ring, and a murder.
