Seventeen-year-old Vanessa is about to get a new life—whether she wants one or not. With a best friend keeping a crazy big secret from her and her parents rubbing their perfect high school love story in her rocky relationship's face, she doesn't have any more cares to give. So when Adam, a ghost who calls himself an Unfortunate, decides to introduce himself in the middle of an argument with her boyfriend, she is less than impressed.

If it wasn't for his persistence and her own guilt, she would've continued ignoring him until he went away. Upon talking to him, Adam explains he died an unfortunate death six years ago and Vanessa is his Match - the one who can help him earn his second chance at life by committing random acts of kindness.

Vanessa is reluctant to help a ghost who may just be in her head. However, if she succeeds in treating others with kindness, Adam will be reborn in time to bring her to prom. If she remains stuck in her ways, he won’t live to see another day.
