To the cheerfully clueless Ethan, it seems like his overbearing mother and older brother are hell bent on sabotaging his entire life. The only person who seems to understand him is high school hottie Madison-not the real Madison, but the life sized cutout of her that's affixed to Ethan's closet door. When things at home become unbearable, Ethan heads out to California to spend the summer with his cousins. An already complicated situation spirals hopelessly out of control, however, when it becomes unmistakably apparent that Ethan's cousin Cleo wants to be more than just family.
