Sick of her parents bickering about money and missing her bosom buddy, Gwen finds a boyfriend and mingles with some horny out-of-townees. Now fifteen, she's discovered that summer can be fun even if Lise isn't there. Then suddenly, Lise shows up at Gwen's house uninvited to stay for a couple of weeks. The following days are filled with unexpected surprises, causing the girls to reevaluate the importance of their friendship and the nature of their teenage anxieties.
