Liv and her best friends Travis and April have just started their last year of high school and things have gotten complicated-Liv has feelings for Travis, April is getting into trouble already, and Travis has a new girlfriend. But then Liv's mom reveals a long-buried secret about Liv's father, who took his own life when Liv was only two, and her life is turned totally upside down.

Reminded of unresolved trauma, Liv's mom starts drinking heavily and Liv is haunted by the thought that her parents could have had good lives if they had never met. When Liv visits the antique shop of Travis's grandpa, she discovers a grandfather clock they suspect can transport people back in time. As Liv's life becomes increasingly chaotic, she's forced to decide: will she travel back in time to stop her parents' complicated relationship, or will she endure an uncertain future?
