The film is inspired by the true-to-life story of the discovery of the long-lost “Opus 28” manuscript from Norwegian composer Johan Halvorsen, originally performed in 1909 by Canadian violinist Kathleen Parlow, to whom the piece was dedicated. Campbell portrays a student who seeks to complete her thesis on Parlow by organizing a public performance of “Opus 28” from Toronto to Oslo. The cast includes Dueñas, Melanie Scheiner, Eve Duranceau, Maxim Gaudette, Rosa-Johan Uddoh, and Eileen Davies.
该音乐会活动由剧集主角Erika Henningsen主持，于纽约著名的Majestic Theater举行。音乐会现场将演绎《Hazbin Hotel》第一季和第二季的热门歌曲，表演者包括Erika Henningsen、Blake Roman、Amir Talai、Christian Borle、Jessica Vosk、Jeremy Jordan和Krystina Alabado，特别嘉宾包括Stephanie Beatriz、Kimiko Glenn、Vivienne Medrano、Sam Haft和Richard Horvitz。
