Lacey Chabert is promising fans a good time when it comes to her new Christmas film She’s Making a List.

In the film, the Mean Girls star plays Isabel, a Naughty or Nice list inspector, who has to determine whether mischievous 11-year-old Charlie (Cadence Compton) is naughty. But while doing so, she falls for Charlie’s widower dad Jason.

Chabert says the film will “put a little bit of goodness into the world” and leav fans uplifted.

“This one is definitely very funny in parts, but it’s also very poignant at the same time,” Chabert told Us Weekly.

“It’s not just a romantic story line in the film. I mean, obviously there is one, and people love to tune in for that, but it’s more than that,” she explained. “It’s the relationship that she ends up having with [Jason’s daughter] Charlie, the child that she’s there to observe, and she realizes the common bond and the common ground that they both share.”

Sharing more about the plot, she said, “While being very poignant, of course, it’s all still really funny, because she’s an inspector. I have lots of different disguises and ways that I try to blend in. Ways that I’m very unsuccessful [at] blending in. It’s just really fun.”

She’s Making a List will be released on Hallmark Channel on Saturday, December 6.
