A single mother becomes involved with a mysterious man who consumes moments of her life, leading her to question her choices, and whether they can-or should-be undone. When Chloe begins a passionate relationship with a traveling businessman named Heath Doran, her life immediately changes for the better, and not just because she's getting laid. Friends thought long lost return, and new opportunities suddenly present themselves out of nowhere. Soon, however, she begins experiencing horrific encounters with ghostly beings eventually revealed to be the echoes of moments she has somehow no longer lived. Terrified at the realization that her past is being rewritten and that Heath is not who-or even what-he seems to be, Chloe must find a way to take back the seconds, minutes, and hours stolen by the alien chronophage masquerading as her new lover. But before she can act, Heath has one last surprise for her: a chance to undo the brief sexual encounter that turned her into a single mother sixteen years ago.
