Charlie the princess of Hell, as she pursues her seemingly impossible goal of rehabilitating demons to peacefully reduce overpopulation in her kingdom. After a yearly extermination imposed by angels, She opens a hotel in hopes that patients will be "checking out" into Heaven. While most of Hell mocks her goal, her devoted partner Vaggie, their infant son Y/N, and their first test subject, adult film-star Angel Dust, stick by her side. When a powerful entity known as the "Radio Demon" reaches out to Charlie to assist in her endeavors, her crazy dream is given a chance to become a reality.
