The room at the end of the hall

When Billie Eilish rents a private mansion to finish her next album, she discovers a hidden door that only appears when she writes from a place of truth. Inside, she finds Nat Wolff - but he doesn't remember how he got there, and he only exists when the room does. As their connection deepens, Billie begins to question what's real, what's imagined, and whether love can survive in a space that disappears with the dawn.
