His addiction has led to an obsession with a particular performer, Dani Darling. One day, Bill finds a new student has joined his class whom he is convinced is in fact Dani Darling herself. When Bill develops a fixation on finding out the truth, he finds his life unraveling as he and this student are sent down a dark spiral.
