Leo doesn't let anybody in. Ever. Why, when people will just leave you, anyway? Carter, on the other hand, has a way of forcing herself in. Especially when it comes to Leo, who she can't help but feel a tinge of curiosity with. What Leo doesn't know, is Carter isn't as carefree and naive as she lets him believe- she's got her own people she's afraid to face. Together, Leo overcomes his hesitancy of letting people in, and Carter revisits the past she left behind years ago. This is the summer they let go of their fears and, with the help of one another, learn to let go of the past, as well.
