On a downward spiral, Devon is saved by Lucy (Lily Sullivan) a mysterious girl who is just as impulsive and romantic as he is. After one day together, they fall completely in love. Devon then arranges for Nick to meet her, but Lucy doesn't show. They try to find her but her apartment is empty. Nick suspects that Lucy is a delusion, while Devon, desperate to prove his sanity, discovers a note that she wrote him: meet me in Sydney. And Devon sets off on an epic, cross-country journey to find her; the girl of his dreams... who may be all in his head.
