On the night of yet another disappointing New Year's Eve, Tim's father reveals a family secret: the men of their line can travel through time within their own lives. They cannot alter history, but they can repeat and correct their own moments. Tim decides to use this gift for what matters most to him, winning the love of Mary and building a life with her, though he soon discovers that not even the power to rewind the days protects against inevitable losses. Richard Curtis crafts a bittersweet romantic comedy that, beneath its fantastical premise, hides a moving lesson about savoring the everyday.
