Sam Haft and Andrew Underberg contribute original music and lyrics to an adult-oriented animated comedy, which seeks to transfer rehabilitated demons from Hell to the pearly gates of Heaven. The plan's mastermind is Charlie Morningstar (voiced by Erika Henningsen), the princess of Hell, who need a radical plan to avoid overpopulation in her kingdom which is typically solved with a yearly extermination imposed by the angels. Charlie's solution is to build a hotel with her devoted partner Vaggie (Stephanie Beatriz), where patrons can complete their ascent to Heaven. Adult film star Angel Dust (Blake Roman) is the program's test case and Charlie receives additional support from a mysterious and powerful entity Alastor (Amir Talai), known as the Radio Demon
