In Seattle, strait-laced Matt Leland falls in love with Casey Roberts, the new girl at their high school who's from Chicago. They begin a sexual relationship. His father disapproves of this and her parents try to stop them from continuing to see each other. She deliberately sets off the fire alarm at school, knowing that there is no fire there, and is subsequently suspended. She has an argument with her parents when they tell her they are sending her to a boarding school. She takes an overdose and her parents subsequently arrange to have her committed. Matt helps Casey escape from an acute psychiatric ward, and as they run away they both deal with her borderline personality disorder.
Casey is eccentric in nature. Her impulsiveness and extreme risk-taking attitude and behavior is attributed to her illness, in which she experiences severe highs and lows of emotion. Her frequent intense feelings, of passion towards Matt and of fear and destructiveness, dominate her persona. Throughout the relationship, Matt selflessly puts her needs before his. The severity of this increases as her mental state worsens.
