Cara is an aspiring ghost hunter, determined to show she's more than a high school outcast by finding proof of the supernatural. Then she stumbles upon the spirit of Aiden, a popular boy who died a year ago. Yet Aiden has his own plan to help his reclusive sister Meredith recover from his death. And he's decided Cara's the girl for the job. Cara agrees to ask Meredith out in exchange for Aiden helping her prove there's life beyond death. No dates, no ghost. Wooing the standoffish Meredith isn't going to be easy, however. With Aiden's coaching, Cara slowly wins Meredith over - and finds herself really falling for her in the process. But as Meredith gets happier and Aiden's mission nears completion, his ghost begins to fade. Can Cara carry on dating and deceiving Meredith - or will she have to give up the ghost?
