Cooper Harris is determined to get his fiancée, Celina Davenport, to say "I do" before the New Year. While she's focused on creating a magical Christmas for their seven-month-old daughter, Via, all Cooper is asking from Santa is to finally be able to call Celina his wife.
Celina wants nothing more than to become Mrs. Cooper Harris, except ties to her past keep her from making the leap. Hoping to lift her Christmas spirits, with the rest of the SCVC Taskforce lending a hand, she convinces Cooper to play Santa at a holiday fundraiser for the Aslan Children’s Hospital.
The party takes a deadly turn when a cartel leader wanted by the US government crashes the guest list with his terminally ill daughter, taking everyone hostage. With the lives of so many on the line - including his own family - Cooper will have to pull a Christmas miracle from Santa's toy sack to help the sick girl, while bringing an end to her father's reign of terror.
