Fifteen-year-old Camille (Lola Creton) is a serious girl who has fallen in love with the cheerful Sullivan (Sebastian Urzendowsky), an older boy who returns her feelings, mostly, but wants to be free to explore the world. When he leaves her to travel, she is devastated, but develops over the following years, into a more fully formed woman, with new interests and a new love - and the possibility that she'll be less defenseless when Sullivan enters her life again.
