If you could turn back the clock, would you choose a different life? Ben usually loves the month of December, but this year, with his relationship with Daphne on the rocks, it's missing its usual magic.
And then his old friend Alice gets back in touch. Ben's always thought of Alice as the one that got away, and he can't help but wonder: what if he'd done things differently all those years ago? He never imagines he might get to find out... but when a stranger sells Ben a mysterious watch one freezing winter's night, he's astonished to wake up the next morning on 5th December 2005: the day he first kissed Daphne, leaving Alice behind. Now Ben must make the biggest decision of his life, all over again. But this time around, will he finally find the courage to follow his heart? Two loves. Two lives.
