Sixteen-year-old Elizabeth Showers, best friend of Kristin Gregory, is sent to the hospital when a dodgeball strikes her in the head one day in gym class. There's only one question on the table: Who did it? It couldn't have been her best friend, Kristin, right? Or could it have? That's what everyone seems to think. In order to prevent expulsion, Kristin is faced with the challenge of proving herself innocent to the entire school in a mock trial, in which she rivals her archenemy and Queen Bee of the school - Eliza. Along the way, she gets help from one of the football team's hottest players and also her ex-boyfriend. But can she convince Elizabeth that she was not responsible for her injury and stop her from joining forces with Eliza? A girl can only hope.
