A corporate jingle writer is on the verge of abandoning her songwriting dreams for good when she mistakenly hands over an old love song to the man who broke her heart, a famous country singer is looking for his next hit.

Sisters Kristina (Deborah Joy Winans) and Vicky (Lisa Michelle Cornelius) receive an early Christmas gift—a luxurious vacation at an exclusive resort—from their Aunt Debbie (Marium Carvell), who hopes to bring them together after they've grown apart since their mother’s death. The sisters are less than thrilled by the idea of spending time together: Vicky loves Christmas, whereas Kristina no longer enjoys the holiday without their mom. With strong convincing from Aunt Debbie, the sisters reluctantly accept her gift. Once they arrive at the resort, Kristina and Vicky run into Reginé (Kyana Teresa), a famous singer and one-time best friend who left them behind when fame came calling.

When Grace's former classmate (and crush) Ryan arrives home for Christmas, Grace's best friend initiates "Operation Mistletoe" to get them together.
