The year isn't starting out too well for Toronto high school senior Katherine Boatman. Not only has her oldest friend ditched her, her grandmother died, leaving a void of goodness in her life. While overwhelmed with sadness and self-doubt, Katherine unexpectedly finds new love, both for Toronto's underground music scene and for her would-be savior: a straight-edge, loudmouthed misfit named Marie. As Katherine seeks comfort in jagged guitars, mind-reading poets and honest conversations, she struggles to figure out not only what she and Marie might mean to each other, but also what it truly means to be good.
