Arthur suffers from peladophobia, the irrational fear of bald people. He attends therapy, where we meet Brett, his therapist. In therapy, he relives his shiny-scalped nightmares, from failed job interviews to surreal exposure exercises that blur the line between dream and reality. As his treatment escalates into a full musical spectacle, Arthur must face the ultimate test: shaving his own head and joining the chorus of baldness he fears most.
