A chance meeting in a coffee shop begins an eventful evening for fifteen-year-old schoolboy Scott Williams. Dressed in full school uniform, and in town to buy a book, he finds himself accosted by a strange girl, dressed boyishly, with red flecks in her hair. Although they are the same age, she is far more streetwise than the naive Scott; her life almost the reverse of the boy's. Scott lives in an affluent area, with his parents and sister; Jet lives in a second floor flat with her alcoholic single mother. Scott is at a private school, Jet's education is the streets she spends her nights walking. For some inexplicable reason, instead of ignoring Jet and catching the next bus home, Scott allows the girl to manipulate him into missing it. As the evening becomes more bizarre, he becomes mesmerized by the world she inhabits. Sadly the evening will have tragic consequences for both of them.
