For the first time since their friendship began, four best friends will be separated for a summer. Despite being of various shapes and sizes, each one of them fits perfectly into a particular pair of secondhand jeans. And so, to keep in touch, they share the pair of faded and worn jeans. Each girl keeps the pair of jeans for a week before passing it on to the next person. Through this, the girls are also able to share the individual adventures and experiences that they have while they're apart.
