Please answer the following question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Bewitched Movie plot: Jack Wyatt is a narcissistic actor who is approached to play the role of Darrin in a remake of the 1960s sitcom Bewitched, but insists that an unknown play Samantha. Isabel Bigelow is an actual witch who decides she wants to be normal and moves to Los Angeles to start a new life and becomes friends with her neighbor Maria. She goes to a bookstore to learn how to get a job after seeing an advertisement of Ed McMahon on TV. Jack happens to be at the same bookstore after attending some failed Samantha auditions. Jack spots Isabel and persuades her to audition. At the same time, while she's trying to settle into her new life, Isabel's intrusive father Nigel keeps appearing to convince her to return home, despite several rejections from Isabel. After Isabel impresses the show's producers and writers, Jack finally convinces Isabel to join the show. Also joining the show is legendary actress Iris Smythson as Endora. After a successful taping of the pilot, Isabel happens to overhear a conversation Jack is having with his agent Ritchie. They are talking about how they tricked Isabel to appear without having any lines. Furious, Isabel storms off with Maria and new friend Nina close behind. She decides she only has three choices: quit, get mad, or live with it. Instead, Isabel's Aunt Clara visits and aids Isabel in casting a spell on Jack in order to make him fall in love with her. At the same time, Nigel is introduced to Iris and becomes infatuated with her. The hex works and Jack becomes love struck by Isabel, insisting on several script changes to give her some dialogue and jokes, ignoring statements from test groups preferring Isabel over him. Jack's affection for Isabel grows and he asks her out on a date, making Isabel forget about the hex. But when he brings her home, she remembers and reverses it back to when she and Aunt Clara cast it. The next day, rather than the events the hex presented, Jack is outraged by the scores he received and takes his anger out on Isabel, who lashes back at him. Ritchie fires her,... My question: What does Isabel discover as she goes along?
A:
She was tricked to appear without having any lines
