Lori is beautiful, smart, and athletic, but she can't stand up for herself no matter the situation -- especially if it involves defying her parents' expectations. Her best friend, Faye, is almost her exact opposite: happy to stand up for herself and take what she wants -- unless it involves her brother, Adam. When the girls get a chance to go on a week-long trip to an exotic resort with Adam and four of his friends, they jump at the chance to trade their problems for sunshine, bikinis, and sunglasses. However, things get messy... fast. Soon everyone in the group is fighting and relationships are being ripped apart. Going on the best vacation ever may turn out to be the worst decision ever.
