When Olivia awakes in a hospital bed following a near-fatal car accident, she can't remember how she got there. She figures it's because she was in a coma for a week, but as time goes on, she realizes she's lost more than just the last week of her life--she's lost all memory of events that happened years ago. Gone is any recollection of starting or graduating high school; the prom; or her steady boyfriend Matt. Trying to figure out who she is feels impossible when everyone keeps telling her who she was.
