Devoted classical guitar players, Cate and Cal are childhood friends newly smitten by love - until a devastating car accident rips Cal out of Cate's life forever. Blaming herself for the horrific tragedy and struggling to surface from her despair, Cate spirals downhill in a desperate attempt to ease her pain. Fellow student David Bennet might look like the school's golden boy, but underneath the surface the popular athlete battles demons of his own. Racked with survivor's guilt after his brother's suicide, things get worse when tragedy darkens his world again - but connecting with Cate, his sister's longtime babysitter, starts bringing the light back in. As Cate and David grow closer, the two shattered teenagers learn to examine the pieces of their lives...and, together, find a way to be whole again.
