Nick, a popular and well-liked high school junior, is looking forward to another outstanding year, coasting toward graduation and a stellar football career like his dad. This all changes when a new girl, Cat, enrolls in school and says they were once boyfriend and girlfriend—years ago! But worse still, Nick begins remembering WWII and a boy named Jean Claude, who, while enrolled in a military academy in a small French town, was in love with a gypsy girl, Chaton. Nick's perfect life begins to unravel bit by bit. And he's starting to be attracted to Cat, much to the disbelief and anger of his class-president girlfriend, Emily. In one short moment, Cat has turned his life into a catastrophe.
