But before she takes her life, she wants to make amends with the people she's hurt in the past, which means she must reconcile with her ex-boyfriend, neighbour and childhood best friend, Shane Lawson, who she cheated on when she was sixteen. But when Shane keeps pushing Mia away, telling her she ruined something special, Mia is stuck trying to get Shane to forgive her before it's too late.
