In an attempt to win back her ex-boyfriend on Christmas Eve, Kate ends up ruining her blind date with Miles (Mark-Paul Gosselaar), a handsome guy she’s been set up with. In a strange twist of fate, Kate is given the chance to re-live Christmas Eve twelve times! Kate decides to embrace what Christmas Eve has given her — a loving family, great friends and Miles, who turns out to be a great guy! However, just as she seems to think she has gotten it right, the clock strikes midnight and Kate must live Christmas Eve once again. Under these weird new circumstances, Kate learns to take risks and enjoy what she’s been given. Thanks to the gift of Christmas Eve, Kate finds happiness by finally trusting fate.

Katie (Lucy Hale) and Sara (Phoebe Strole) have been friends since childhood. They enter college together, where Katie is a prized legacy candidate for the Delta sorority, which was co-founded decades ago by her mother, Lutie (Courtney Thorne-Smith) and Summer (Faith Ford), whose own daughter Gwen (Amanda Schull) now leads the Deltas on campus. Events occur during pledge week to cause a rift between Katie and the Deltas, which leaves Sara as a Delta pledge and Katie out in the cold. Katie joins the rival Kappa sorority, and the rivalry splits not just Katie and Sara, but extends all the way into the Delta alumnae association led by Lutie and Summer.

Two women plot revenge against the woman marrying their friend’s ex-boyfriend.
