The film is about a girl named Emma, whose father and her high school frenemy start dating, so she embarks on a mission to break up relationship between the happy couple.

Christmas Is Cancelled was theatrically released on December 16, 2021, and was produced by Particular Crowd, MarVista Entertainment, Line Film Company and Lionsgate.

She feels obligated to take care of her dad, Jack (Dermot Mulroney), and when she heads home after a research trip to spend the holidays with him, discovers some incredibly distressing news: that her father is dating her high school frenemy Brandy (Janel Parrish).

With the reluctant support of her best friend Charlyne (Emilie Modaff) and a hunky bartender named Josh (Michael Naizu), Emma tries to pull off some relatively mundane schemes to split up Brandy and her dad.

Emma ignores her own budding connection with Josh in favor of her obsession with ruining her dad's relationship, and puts Charlyne in an uncomfortable position at the same time.
