The Mistle-Tones is a made-for-TV movie musical that premiered on December 9, 2012 as part of ABC Family's 25 Days of Christmas.

Holly is excited to audition for the Snow Belles, a Christmas-themed pop group founded by her late mother.

However, lead Belles singer Marci denies Holly a chance to audition when she shows up late.

Nevertheless, Holly takes to the stage and delivers a sensational audition and is upset when Marci passes her over in favor of Staci.

The manager decides to hold auditions and a competition as a publicity stunt and agrees to let Holly's group into the show.

Holly recruits a group of her coworkers including her best friend, AJ, large and lovable Larry, and the shy HR manager, Bernie.

Holly records his performance and uses it to blackmail him into helping her turn the group into solid competition for the Snow Belles.

It is during one of the last rehearsals where Staci who is hiding in the warehouse, videos the Mistle Tones with Nick singing along.

Having seen a video of the group's performance, Marci begins to see Holly as a potential threat and offers her a spot in the Belles to ensure the Mistle-Tones won't compete.

Nick, however, interrupts her by singing "Winter Wonderland" and leading the group in an impromptu performance.

However, as Nick is watching Holly get into her car he receives a call from a company executive telling him that he has the promotion and they want him to take over the South Asian division and for him to get on a plane that evening.

When she gets to the bottom of the stairs she hears music and from a distance can see AJ, Larry and Bernie.

He begs her to sing with him and she agrees, dueting with Nick as the town and the Snow Belles enjoy the show.
