Calle and her friends Brea, Lucas, and Matt are on vacation in California for summer break. And nothing goes as planned. Calle is certain that this relaxing trip will bring them closer together with no arguments at all. But boy is she wrong. Will they stay best of friends by the time vacation's over? Or will they go their separate ways when the time gets rough. Because their friendship will depend on it. Boy, being friends on vacation is hard!
