Ruby has woken up from an accident that claims the life of her family, not remembering who she is and loses the ability to speak. With nowhere to go, her doctor takes her into his care.

Even though she doesn't remember anything, there is something about the doctor's son, Tyler. She swears she has seen him before but has no idea where. As she gets to know him, she begins to fall for him. There is just one problem: he is already dating someone and Ruby knows she doesn't have a chance with him, but Tyler might just be the key to remembering everything about herself, as well as the sound of music.
